Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
grep: display correct user/revision for --all in reverse. Also handle multiple occurrences of the same line by storing linestates in an array instead of a dict, and using difflib to compute the difference between linestates.
