You can trap all 3 of the above cases with a header_filter_rules rule
with the regexp

$subject:\s*(\(no[_ ]subject\))?\s*$

but there is a 4th case which this won't get which is the case where
the message contains no Subject: header at all. See
<http://mail.python.org/pipermail/mailman-users/2007-March/056119.html>
fo more information on how to deal with this case.

See <http://docs.python.org/lib/re-syntax.html> for information about
Python regular expressions.
