OR is easy. Just remember that the internal pattern matcher is a clone
of E(extended)grep which uses Extended Regular Expressions (EREs).

Profuse appologies - my mistake, as I use this all the time (esp for
handling subdomains), but for complex things, wherein you are attempting
one rule on one line, and another on the next, you can't easily do an OR.
(Run formail to extract some header info and pipe that to fgrep, then do
another formail on the same line sometime - blech!).
