diff mercurial/hg.py @ 10365:d757bc0c7865

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
interpret repo#name url syntax as branch instead of revision Previously, the name part of an repo#name url was interpreted as a revision, similar to using the --rev option. Now it is instead looked up as a branch first, and if that succeeds all the heads of the branch will be processed instead of just its tip-most head. If the branch lookup fails, it will be assumed to be an revision as before (e.g. for tags).
