Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
revsetbenchmark: add `author(mpm) or author(lmoscovicz)` to the canonical list This matters as `author(mpm)` have a lot of matches evenly split in the repo, while `author(lmoscoviz)` have less match (and later). This changes the execution path of the "or" operator a lot.
