Subject: When receiving an empty mail (no results and no unprocessed lines,
 but possibly 'ignored' lines, if a lot of 'em were blank) on a
 command-handler address, inform the user that the mail was empty, and how to
 get help. Based on SF patch #522080, Respond sensibly to blank -request
 email, by Seb Wills.
