Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Fix tests for memorydb and anydbm backends The anydbm backend silently drops properties in the journal that are not in the database during serialisation. The memorydb backend (only used for testing) cannot deal with user changes (re-open of db under a different user).
