Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
RevlogStream: be aware of existence (not HgDataFile), facilitate use of an added HgDataFile over a commit; Rollback: be more sensitive about file changes (file size is not enough: write/rollback leaves it intact); tests
