annotate mercurial/fancyopts.py @ 174:23057dc57d1b

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
hg merge: abort if there are outstanding changes in the working directory We currently don't support merging from the tip into the working directory, so merge with outstanding local changes is asking for trouble.
