pandoc 0.43 - bug fix release - huge performance improvements

[John MacFarlane]

I've just released pandoc 0.43. The source tarball and Windows
package are available at http://pandoc.googlecode.com/.
It may be a few days before the MacPorts port and debian
package databases have been updated.

The most notable improvements in this release are in performance.
Here are some benchmarks for parsing a 178K test file (the TextMate
manual) in 'strict' mode, on an Intel Core Duo 1.66GHz machine
with 1G RAM:

10.30s Markdown.pl v 1.0.1
15.47s Markdown.pl v 1.0.2b8
5.14s pandoc 0.42
0.91s pandoc 0.43

In addition:

+ LaTeX output is now prettyprinted (wrapped and indented).
+ Fixed bug in LaTeX reader with 4th-level nested lists.
+ Fixed bug in LaTeX parser (command names can't contain digits).
+ Improved --strict compatibility for reference-style links.
+ Fixed inline code parsing so it better accords with Markdown.pl:
` `` ` is now parsed as <code>``</code>.
+ Markdown writer escapes paragraphs that begin like list items.
