annotate Python/codecs.c @ 37875:a4c70f3968be

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Merge part of the trunk changes into the p3yk branch. This merges from 43030 (branch-creation time) up to 43067. 43068 and 43069 contain a little swapping action between re.py and sre.py, and this mightily confuses svn merge, so later changes are going in separately. This merge should break no additional tests. The last-merged revision is going in a 'last_merge' property on '.' (the branch directory.) Arbitrarily chosen, really; if there's a BCP for this, I couldn't find it, but we can easily change it afterwards ;)
