96ab46529b -- added recursion limit (currently ~10,000 levels)
-- improved error messages
-- factored out SRE_COUNT; the same code is used by
   SRE_OP_REPEAT_ONE_TEMPLATE
-- minor cleanups

2f2c67d7e5 -- fixed width calculations for alternations
-- fixed literal check in branch operator
   (this broke test_tokenize, as reported by Mark Favas)
-- added REPEAT_ONE operator (still not enabled, though)
-- added some debugging stuff (maxlevel)

29c4ba9ada SRE 0.9.8: passes the entire test suite
-- reverted REPEAT operator to use "repeat context" strategy
   (from 0.8.X), but done right this time.
-- got rid of backtracking stack; use nested SRE_MATCH calls
   instead (should probably put it back again in 0.9.9 ;-)
-- properly reset state in scanner mode
-- don't use aggressive inlining by default

72b82ba16d - fixed grouping error bug

6f01398236 - added lookbehind support (?<=pattern), (?<!pattern).
the pattern must have a fixed width.

- got rid of array-module dependencies; the match pro-
  gram is now stored inside the pattern object, rather
  than in an extra string buffer.

- cleaned up a various of potential leaks, api abuses,
  and other minors in the engine module.

- use mal's new isalnum macro, rather than my own work-
  around.

- untabified test_sre.py.  seems like I removed a couple
  of trailing spaces in the process...

c2301730b8 - experimental: added two new attributes to the match object:
"lastgroup" is the name of the last matched capturing group,
  "lastindex" is the index of the same group.  if no group was
  matched, both attributes are set to None.

  the (?P#) feature will be removed in the next relase.

7cafe4d7e4 - actually enabled charset anchors in the engine (still not
used by the code generator)

- changed max repeat value in engine (to match earlier array fix)

- added experimental "which part matched?" mechanism to sre; see
  http://hem.passagen.se/eff/2000_07_01_bot-archive.htm#416954
  or python-dev for details.

8094611eb8 - fixed another split problem
(those semantics are weird...)

- got rid of $Id$'s (for the moment, at least).  in other
  words, there should be no more "empty" checkins.

- internal: some minor cleanups.

be2211e940 - fixed split
(test_sre still complains about split, but that's caused by
  the group reset bug, not split itself)

- added more mark slots
  (should be dynamically allocated, but 100 is better than 32.
  and checking for the upper limit is better than overwriting
  the memory ;-)

- internal: renamed the cursor helper class

- internal: removed some bloat from sre_compile

b389df3402 - renamed "tolower" hook (it happened to work with
my compiler, but not on guido's box...)
