It's good practice not to use codes 1-2 for user errors.
Also, we used 65 for two different errors.
- PandocAppError was 1, is now 4
- PandocOptionError was 2, is now 6
- PandocMakePDFError was 65, is now 66
Deprecate --base-heading-level.
The new option does everything the old one does, but also
allows negative shifts. It also promotes the document
metadata (if not null) to a level-1 heading with a +1 shift,
and demotes an initial level-1 heading to document metadata
with a -1 shift. This supports converting documents that
use an initial level-1 heading for the document title.
Closes#5615.
* Org reader: allow the `-i` switch to ignore leading spaces.
* Org reader: handle awkwardly-aligned code blocks within lists.
Code blocks in Org lists must have their #+BEGIN_ aligned in a
reasonable way, but their other components can be positioned otherwise.
Text.Pandoc.Shared:
+ Remove `Element` type [API change]
+ Remove `makeHierarchicalize` [API change]
+ Add `makeSections` [API change]
+ Export `deLink` [API change]
Now that we have Divs, we can use them to represent the structure
of sections, and we don't need a special Element type.
`makeSections` reorganizes a block list, adding Divs with
class `section` around sections, and adding numbering
if needed.
This change also fixes some longstanding issues recognizing
section structure when the document contains Divs.
Closes#3057, see also #997.
All writers have been changed to use `makeSections`.
Note that in the process we have reverted the change
c1d058aeb1
made in response to #5168, which I'm not completely
sure was a good idea.
Lua modules have also been adjusted accordingly.
Existing lua filters that use `hierarchicalize` will
need to be rewritten to use `make_sections`.

This reverts commit 345b33762e.
The structure
```
<h1>one</h1>
<div>
<h1>two</h1>
</div>
```
should create two coordinate sections, not a section with
a subsection. Now it does.
Extends #3057.
Previously Divs were opaque to hierarchicalize, so headings
inside divs didn't get into the table of contents, for
example (#3057).
Now hierarchicalize treats Divs as sections when appropriate.
For example, these structures both yield a section and a
subsection:
``` html
<div>
<h1>one</h1>
<div>
<h2>two</h2>
</div>
</div>
```
``` html
<div>
<h1>one</h1>
<div>
<h1>two</h1>
</div>
</div>
```
Note that
``` html
<h1>one</h1>
<div>
<h2>two</h2>
</div>
<h1>three</h1>
```
gets parsed as the structure
one
two
three
which may not always be desirable.
Closes#3057.
