annotate src/util.c @ 500:614a3177b15c noffle tip

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Add mail-from option. Some modern mail systems will try and ensure the sender email is a legitimate address. Which will fail if there isn't such an address.
