PR #5884.
+ Use pandoc-types 1.20 and texmath 0.12.
+ Text is now used instead of String, with a few exceptions.
+ In the MediaBag module, some of the types using Strings
were switched to use FilePath instead (not Text).
+ In the Parsing module, new parsers `manyChar`, `many1Char`,
`manyTillChar`, `many1TillChar`, `many1Till`, `manyUntil`,
`mantyUntilChar` have been added: these are like their
unsuffixed counterparts but pack some or all of their output.
+ `glob` in Text.Pandoc.Class still takes String since it seems
to be intended as an interface to Glob, which uses strings.
It seems to be used only once in the package, in the EPUB writer,
so that is not hard to change.
* Require recent doctemplates. It is more flexible and
supports partials.
* Changed type of writerTemplate to Maybe Template instead
of Maybe String.
* Remove code from the LaTeX, Docbook, and JATS writers that looked in
the template for strings to determine whether it is a book or an
article, or whether csquotes is used. This was always kludgy and
unreliable. To use csquotes for LaTeX, set `csquotes` in your
variables or metadata. It is no longer sufficient to put
`\usepackage{csquotes}` in your template or header includes.
To specify a book style, use the `documentclass` variable or
`--top-level-division`.
* Change template code to use new API for doctemplates.
Quite a few modules were missing copyright notices.
This commit adds copyright notices everywhere via haddock module
headers. The old license boilerplate comment is redundant with this and has
been removed.
Update copyright years to 2019.
Closes#4592.
* XML.toEntities: changed type to Text -> Text.
* Shared.tabFilter -- fixed so it strips out CRs as before.
* Modified writers to take Text.
* Updated tests, benchmarks, trypandoc.
[API change]
Closes#3731.
