annotate mercurial/sshrepo.py @ 3409:1ae738bacf74

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Fixed page overlap for file revision links in hgweb. This is another step to fix issue189, but currently the file revision numbers are read as changeset revision numbers, so the link will point to the wrong revision.
