This makes its default behaviour useful again (issue108), and
changes it search the entire repository by default (instead
of just the cwd), just like all other commands.
It also hides issue204 by default, but you'll still see the
same behaviour if you give it a relpath: pattern.
(including small changes to revert and backout to not show these stats
with the exception of backout --merge)
Show update stats (unless -q), e.g.:
K files updated, L files merged, M files removed, N files unresolved
Inform the user what to do after a merge:
(branch merge, don't forget to commit)
Inform the user what to do if a branch merge failed:
There are unresolved merges, you can redo the full merge using:
hg update -C X
hg merge Y
Inform the user what to do if a working directory merge failed:
There are unresolved merges with locally modified files.
