f04df62db1 Changed definition of 'enclosed' in Text.Pandoc.Shared so that
'try' is not automatically applied to the 'end' parser.
Added 'try' in calls to 'enclosed' where needed.  Slight speed
increase.

1d8fe2653a Performance improvements:
+ Rearranged parsers in definition of 'inline' so that the most
frequently used would (by and large) be tried first.
+ Removed some unneeded 'try's.
+ Removed tabchar parser, as whitespace handles tabs anyway.
+ All in all, these changes, together with the last two commits,
  cut almost in half the time it takes pandoc to parse a large test file.

f11360f50e Added new rule for enhanced markdown ordered lists: if the list marker
is a capital letter followed by a period (including a single-letter
capital roman numeral), then it must be followed by at least two spaces.
The point of this is to avoid accidentally treating people's initials as
list markers: a paragraph may begin:

    B. Russell was an English philosopher.

and this shouldn't be treated as a list.

Modified Markdown reader and README documentation.
Added a test case.

84aa875bdb Changes to Markdown reader for better conformity to the
Markdown test suite under --strict:
+ Removed check for a following setext header in endline.
  A full test is too inefficient (doubles benchmark time), and
  the substitute we had before is not 100% accurate.
+ Don't use Code elements for autolinks if --strict specified.

e48f046aa0 + Fixed bug in markdown ordered list parsing. The problem was
that anyOrderedListStart did not check for a space following the
  ordered list marker. So, 'A.B. 2007' would be parsed as a list item,
  then fail because of the lack of space after 'A.' (required by
  orderedListStart). Resolves Issue #22.
+ Fixed a similar problem in RST reader.
+ Added regression test.

a8e2199034 Major code cleanup in all modules. (Removed unneeded imports,
reformatted, etc.)  More major changes are documented below:

+ Removed Text.Pandoc.ParserCombinators and moved all its definitions
  to Text.Pandoc.Shared.
+ In Text.Pandoc.Shared:
  - Removed unneeded 'try' in blanklines.
  - Removed endsWith function and rewrote functions to use isSuffixOf instead.
  - Added >>~ combinator.
  - Rewrote stripTrailingNewlines, removeLeadingSpaces.
+ Moved Text.Pandoc.Entities -> Text.Pandoc.CharacterReferences.
  - Removed unneeded functions charToEntity, charToNumericalEntity.
  - Renamed functions using proper terminology (character references,
    not entities).  decodeEntities -> decodeCharacterReferences,
    characterEntity -> characterReference.
  - Moved escapeStringToXML to Docbook writer, which is the only thing
    that uses it.
  - Removed old entity parser in HTML and Markdown readers; replaced with
    new charRef parser in Text.Pandoc.Shared.
+ Fixed accent bug in Text.Pandoc.Readers.LaTeX:  \^{} now correctly
  parses as a '^' character.
+ Text.Pandoc.ASCIIMathML is no longer an exported module.

e814a3f6d2 Major change in the way ordered lists are handled:
+ The changes are documented in README, under Lists.
+ The OrderedList block element now stores information
  about list number style, list number delimiter, and
  starting number.
+ The readers parse this information, when possible.
+ The writers use this information to style ordered
  lists.
+ Test suites have been changed accordingly.

Motivation:  It's often useful to start lists with
numbers other than 1, and to have control over the
style of the list.

Added to Text.Pandoc.Shared:
+ camelCaseToHyphenated
+ toRomanNumeral
+ anyOrderedListMarker
+ orderedListMarker
+ orderedListMarkers

Added to Text.Pandoc.ParserCombinators:
+ charsInBalanced'
+ withHorizDisplacement
+ romanNumeral

RST writer:
+ Force blank line before lists, so that sublists will be handled
  correctly.

LaTeX reader:
+ Fixed bug in parsing of footnotes containing multiple paragraphs,
  introduced by use of charsInBalanced.  Fix: use charsInBalanced'
  instead.

LaTeX header:
+ use mathletters option in ucs package, so that basic unicode Greek
  letters will work properly.

7e1370aa87 Markdown reader: Added inlinesInBalanced parser combinator to
unify treatment of embedded brackets in links and inline footnotes.
Note that the solution adopted here causes one of John Gruber's
markdown tests to fail:
  [with_underscore](/url/with_underscore)
Here the whole phrase "underscore](/url/with" is treated as
emphasized. The previous version of the markdown reader handled
this the way Gruber's script handles it, but it ran into trouble
on the following:
  [link with verbatim `]`](/url)
where the inner ] was treated as the end of the reference link
label. I don't see any good way to handle both cases in the framework
of pandoc, so I choose to require an escape in the first example:
  [with\_underscore](/url/with_underscore)

f9c988e703 Fixed bug in Markdown reader: links in footnotes were not
being processed.  Solution:  three-stage parse.  First, get
all the reference keys and add information to state.  Next,
get all the notes and add information to state.  (Reference
keys may be needed at this stage.)  Finally, parse everything
else.

cf081435ff Changed definition list syntax in markdown reader and simplified
the parsing code. A colon is now required before every block in a
definition. This fixes a problem with the old syntax, in which the last
block in the following was ambiguous between a regular paragraph in the
definition and a code block following the definition list:

term
:   definition

    is this code or more definition?

485fa81559 Resolved issue #10: instead of adding "\n\n" to the
end of strings in Main, do it in readMarkdown and readRST.
(Note: the point of this is to ensure that a block at the
end of the file gets treated as if it has blank space after
it, which is generally what is wanted.)

23df0ed176 Extensive changes stemming from a rethinking of the Pandoc data
structure. Key and Note blocks have been removed. Link and image URLs
are now stored directly in Link and Image inlines, and note blocks
are stored in Note inlines. This requires changes in both parsers
and writers. Markdown and RST parsers need to extract data from key
and note blocks and insert them into the relevant inline elements.
Other parsers can be simplified, since there is no longer any need to
construct separate key and note blocks. Markdown, RST, and HTML writers
need to construct lists of notes; Markdown and RST writers need to
construct lists of link references (when the --reference-links option
is specified); and the RST writer needs to construct a list of image
substitution references. All writers have been rewritten to use the
State monad when state is required.  This rewrite yields a small speed
boost and considerably cleaner code. 

* Text/Pandoc/Definition.hs:
  + blocks:  removed Key and Note
  + inlines:  removed NoteRef, added Note
  + modified Target:  there is no longer a 'Ref' target; all targets
    are explicit URL, title pairs

* Text/Pandoc/Shared.hs:

  + Added 'Reference', 'isNoteBlock', 'isKeyBlock', 'isLineClump',
    used in some of the readers.
  + Removed 'generateReference', 'keyTable', 'replaceReferenceLinks',
    'replaceRefLinksBlockList', along with some auxiliary functions
    used only by them.  These are no longer needed, since
    reference links are resolved in the Markdown and RST readers.
  + Moved 'inTags', 'selfClosingTag', 'inTagsSimple', and 'inTagsIndented'
    to the Docbook writer, since that is now the only module that uses
    them.
  + Changed name of 'escapeSGMLString' to 'escapeStringForXML'
  + Added KeyTable and NoteTable types
  + Removed fields from ParserState;  'stateKeyBlocks', 'stateKeysUsed',
    'stateNoteBlocks', 'stateNoteIdentifiers', 'stateInlineLinks'. 
    Added 'stateKeys' and 'stateNotes'.
  + Added clause for Note to 'prettyBlock'.
  + Added 'writerNotes', 'writerReferenceLinks' fields to WriterOptions.

* Text/Pandoc/Entities.hs: Renamed 'escapeSGMLChar' and
  'escapeSGMLString' to 'escapeCharForXML' and 'escapeStringForXML'

* Text/ParserCombinators/Pandoc.hs: Added lineClump parser: parses a raw
  line block up to and including following blank lines.

* Main.hs:  Replaced --inline-links with --reference-links.

* README: 
  + Documented --reference-links and removed description of --inline-links.
  + Added note that footnotes may occur anywhere in the document, but must
    be at the outer level, not embedded in block elements.
  
* man/man1/pandoc.1, man/man1/html2markdown.1: Removed --inline-links
  option, added --reference-links option

* Markdown and RST readers:
  + Rewrote to fit new Pandoc definition.  Since there are no longer
    Note or Key blocks, all note and key blocks are parsed on a first pass
    through the document.  Once tables of notes and keys have been constructed,
    the remaining parts of the document are reassembled and parsed.
  + Refactored link parsers.

* LaTeX and HTML readers: Rewrote to fit new Pandoc definition. Since
  there are no longer Note or Key blocks, notes and references can be
  parsed in a single pass through the document.

* RST, Markdown, and HTML writers: Rewrote using state monad new Pandoc
  and definition. State is used to hold lists of references footnotes to
  and be printed at the end of the document.

* RTF and LaTeX writers: Rewrote using new Pandoc definition. (Because
  of the different treatment of footnotes, the "notes" parameter is no
  longer needed in the block and inline conversion functions.)

* Docbook writer:
  + Moved the functions 'attributeList', 'inTags', 'selfClosingTag',
    'inTagsSimple', 'inTagsIndented' from Text/Pandoc/Shared, since
    they are now used only by the Docbook writer.
  + Rewrote using new Pandoc definition.  (Because of the different
    treatment of footnotes, the "notes" parameter is no longer needed
    in the block and inline conversion functions.)

* Updated test suite

* Throughout:  old haskell98 module names replaced by hierarchical module
  names, e.g. List by Data.List.

* debian/control: Include libghc6-xhtml-dev instead of libghc6-html-dev
  in "Build-Depends."

* cabalize: 
  + Remove haskell98 from BASE_DEPENDS (since now the new hierarchical
    module names are being used throughout)
  + Added mtl to BASE_DEPENDS (needed for state monad)
  + Removed html from GHC66_DEPENDS (not needed since xhtml is now used)

term 2

    Any kind of block may serve as a definition,
    but the first line of each block must be indented.

terms can contain any *inline* elements
    If you want to be lazy, you can just
indent the first line of the definition block.

d5f9b1dbb4 Change in ordered lists in Markdown reader:
+ Lists may begin with lowercase letters only, and only 'a' through
    'n'. Otherwise first initials and page references (e.g., p. 400)
    are too easily parsed as lists.
  + Numbers beginning list items must end with '.' (not ')', which is
    now allowed only after letters).
NOTE:  This change may cause documents to be parsed differently.
Users should take care in upgrading.

87eb8be143 Got rid of two unneeded 'getState's. Note that
lookAhead automatically saves and restores the state.

d3efa4aa8a Use lookAhead parser for the "first pass" looking for
reference keys in Markdown parser, instead of parsing
normally, then using setInput to reset input.  Slight
performance improvement.

ae19b94fd1 Removed followedBy' parser from Text/ParserCombinators/Pandoc,
replacing it with the 'lookAhead' parser from
Text/ParserCombinators/Parsec.

f3437dd27c + Added some needed "try"s before multicharacter parsers,
especially in "option" contexts.
+ Removed the "try" from the "end" parser in "enclosed"
  (Text.Pandoc.Shared).  Now "enclosed" behaves like
  "option", "manyTill", etc.

dc6925542c + Simplified entity handling by removing stringToSGML from Entities.hs.
It is no longer needed now that all entities are processed in the markdown 
  and HTML readers.  All calls to stringToSGML have been replaced by calls
  to encodeEntities.
+ Since inTag's attribute handling already encodes entities, 
  calls to encodeEntities are no longer needed for attribute values, so
  they've been removed.
+ The HTML and Markdown readers now call decodeEntities on all raw
  strings (e.g. authors, dates, link titles), to ensure that no unprocessed
  entities are included in the native representation of the document. 
  (In the HTML reader, most of this work is done by a change in
  extractAttributeName.)
+ The result is a small speed improvement (around 5% on my benchmark)
  and cleaner code.

8e0ad5a006 Cleaned up handling of embedded quotes in link titles.
Now these are stored as a '"' character, not as '&quot;'.
The function escapeLinkTitle in the Markdown writer is
unnecessary and was removed.  Tests modified accordingly.
