* Made ==foo==<!----> create a valid section edit link
* Changed header processing heuristics -- now double-equals signs are generally respected as header starts, and will break template invocations, and single equals signs are respected as header syntax but might not generate a section edit link.
* Stabilise timestamps generated by the parser to avoid diff test false positives
* Fixed msgnw bug. Use RECOVER_ORIG.
* Fixed editintro bug. Cloning the parser in MessageCache has some side-effects that need to be corrected.
* Fixed typo in Parser_DiffTest.php
* General improvements to preprocessorFuzzTest.php
* Fixed breakage of XML output feature in Special:ExpandTemplates
* Reduced stack depth by using an internal stack in expand(), and by having some common code paths (e.g. non-subst double-brace during PST) return objects which can be expanded in that internal stack instead of the PHP stack. This is friendly to xdebug but slightly slower than the original version. Also it probably helps robustness when you don't add 7 stack levels per pair of double braces.
* Profiling indicates that expand and PPD are now good targets for porting to C. Abstracted and refactored the relevant code to allow for a drop-in replacement. A factor of 2 reduction in average-case replaceVariables() time may be possible.
* Verified with preprocessorFuzzTest.php against r29950, updated to allow better PST tests.
* Made parserTests.php respect $wgParserConf
* LST and ParserFunctions need a simultaneous update with the core due to changed interfaces. DOM objects are now wrapped rather than directly exposed.
* Fixed #tag behaviour in preprocess()
* Fixed #tag quote stripping regex
* Made MessageCache::getMessage() never transform its result, that is now left up to the caller.
* A few other minor changes
* Split the PPD stack out to its own class. Verified with a differential fuzz test.
* Added parser tests for Morwen/13 (including new heuristic behaviour) and bug 5678.
* Renamed some LST parser tests
* Fixed <gallery> caption behaviour .It should not generate <pre> when there are spaces at the start. Used recursiveTagParse() instead of parse(), to avoid generation of a limit report, among other things.
* Refactored template loop check
* Updated a couple of parser tests
* Added template recursion depth limit. It needs a small limit, because of exorbitant stack space usage, xdebug compatibility problems, and the potential for O(N^2) memory usage in the template loop check.
* Made these two error messages more obvious in the parser output, with <span class="error"> instead of a comment. This is similar to the #expr error messages, which seem to have been well received by our template programmer community.
* Merged includeonly/noinclude/onlyinclude handling with preprocessToDom(), and used the resulting überparser to fix another section numbering bug: bug 6563. The fix involves putting a template flag "T" into the section parameter of edit links. This flag indicates to extractSections() how <includeonly> etc. should be handled.
If these two changes stick, I'll eventually describe the precise syntactic effects in RELEASE-NOTES.
* Added splitExtNode() for future use in LabeledSectionTransclusion.
* Added parser tests for bug 6563.
* Fixed a bug 529 regression -- uncovered line-start syntax in parser function results was not recognised. Added a parser test for this failure plus another three bug 529 tests for good measure.
* No need for comment stripping in Expr.php anymore
* Updated srvus() to roughly account for these changes
* Gave comment handling its own preprocessor tag, and split off comment handling from extensionSubstitution(). This only applies for the non-HTML modes, since in HTML mode, comments are stripped early.
* Strip comments from template argument names (PPFrame::newChild).
LanguageConverter seems to want $wgParser's uniqPrefix, however
if this is called for a parser cache hit, the parser may not
have ever been initialized in the first place.
Not really sure what the heck is supposed to be going on here...
For now, returning an empty string '' without dying out, but
leaving a stub exception comment in for testing.
* Fixed a bug in extractSections() -- inappropriate expansion of double-brace constructs causing a fatal error under some circumstances (reported by Nikerabbit, thanks)
The original link coloring array used 0 for broken links, and an empty() check which would return true for both missing entries and entries which had been stored explicitly as 0.
r27759 switched it to use class names, but the change of the check to !isset() no longer got the explicit case.
11 previously failing test(s) now PASSING! :)

Use x option on regex so we can break it up for legibility.
PHP doesn't seem to let you concat multiple strings in a constant definition, which is kind of lame, so this seems to be the cleanest way to break it over lines. :P
* Made it possible to configure the parser class being used, via $wgParserConf.
* Moved defines from the top of Parser.php to either class constants or Defines.php
* Added Parser_DiffTest, a differential parser class for regression testing
* Added Parser_OldPP, a parser class which operates like the parser before this commit. I made one breaking change: a bugfix to avoid losing whitespace when adding MWTEMPLATESECTION markers.
* Made internal tidy work with PHP 5
* Added the ability to supply a hook for template fetching via ParserOptions. This is handy for testing.
* Updated parserTests.txt to account for the various breaking changes I made. Removed a few parser tests that no longer test for anything useful.
* Uses hardcoded magic numbers extensively, which is poor practice
* Adds two hooks with no documentation
* Dropping $class unencoded into the HTML output feels like bad practice to me
* A link-by-link coloring plugin sounds like it could be very expensive to begin with; I'm a bit leery of adding in such overhead.
