Hmm, right.  That would work for most use cases.

Downsides:
* according to maildir-deduplicate's upstream, some non-spam mail servers
  fail to assign msgids
* bad threading (direct reply almost always comes first, the mailing list
  copy would be better)
Big fat upside:
* done automatically instead of a [semi-]manual action

The package still has its other uses (mutt doubles mails when you lose
connection after moving stuff, said to be a common failure of mail fetch,
etc) so unless someone else brings another reason I'll continue packaging.


Meow!
