Yeah, magic is bad.  So tempting though.  ;-)

Yow!  The very fact that this needs such a big and complex table
describing it is a big strike against it, IMHO.  (Consider: do you
understand how to use "hg remove" to forget a file?  Me neither.
That's why I was happy to see the "forget" command (re-)added.)

And easy to document, easy to explain, easy to understand.  And it's
consistent.  The only required info to send email should be "To" and
"Subject".

BTW I strongly agree with Mads' suggestion that patchbomb should
typically just tell you what it's going to send and then ask for
confirmation.  The current UI could definitely be improved.
