Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
clone: make sure to use "@" as bookmark and "default" as branch (issue3677) Before this change a bookmark named "default" or a branch named "@" would cause the wrong changeset to be checked out. The change in output of test-hardlinks.t is due to the fact that no unneeded tag lookups for the tags "@" or "default" happen, therefore the cache file is not created.
