I think the patch is fine.

Sorry, but I no longer read every email that passes by due to the amount
of email I now receive, and due to the nature of modern email clients with
their stupid ideas about how to formulate the To: and Cc: headers for
replies[*], I attach no significance to being mentioned in either the To:
or Cc: headers.

Overall, what this means is it's now difficult to attact my attention to
any particular thread.  Sorry about that, I have no solution to this
problem.


* - modern mailers have started to preserve the To: and Cc: headers from
the message being replied to, which means that if I'm mentioned in the
To: header initially, my address stays in the To: header despite the
discussion not being directed _at_ me.  Hence, deciding what to reply to
based on where my address appears in the headers is meaningless with
modern mail clients.
