annotate mercurial/cmdutil.py @ 2874:4ec58b157265

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
refactor text diff/patch code. rename commands.dodiff to patch.diff. rename commands.doexport to patch.export. move some functions from commands to new mercurial.cmdutil module. turn list of diff options into mdiff.diffopts class. patch.diff and patch.export now has clean api for call from 3rd party python code.
