+1 for removing dupes by default.

This patch would be a great additon to "Umbrella" lists.  Most folks assume 
that Umbrella lists work this way anyway...

BTW: I'm all for making it the default.  As someone pointed out earlier, 
Mailman acts as an Adjunct or part of the MTA, so it should follow similar 
rules.  The default for any MTA that I've used is to remove dupes.
