Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Sub filter: fixed incomplete last buffer on partial match. If a pattern was partially matched at a response end, partially matched string wasn't send. E.g., a response "fo" was truncated to an empty response if partially mathed by a pattern "foo".
