Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
pages: get last page by default with RSM: When `max_items` is not used, Pubsub (and thus RSM) is actually returning results in chronological order. As most of time we want latest items first, `getPubsubExtra` now set `before` to get last page by default (the one with most recent items).
