annotate mercurial/sshrepo.py @ 2473:30c267cb4c2f

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
change some repo messages in small ways. move "pushing" and "pulling" after repo create so error message and exit happens before messages printed. fix sshrepo parse error message.
