Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
revset: add parsing rule for key=value pair It will be used as an keyword argument. Note that our "=" operator is left-associative. In general, the assignment operator is right-associative, but we don't care because it isn't allowed to chain "=" operations.
