comparison mercurial/commands.py @ 1254:e6560042b7b8

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Switch cat command to use walk code. The old syntax of "hg cat FILE REV" is now obsolete. Use "hg cat -r REV FILE" instead, as for all other commands.
