Not easily, because trac groups all attachments together instead of
packing them into their submission comments.
In such a case you should write the name of the patch you
Sign-off or Ack. "Unless otherwise noted".
In theory, a patch that solves half the problem only should not get

The check-in comment should be "all of the discussion done on this
check-in", so you get a non-ambiguous bidirectional connection between a
check-in and the discussion that led to this check-in.
If you go through the revisions of v1 and v2, you will find a lot of
stuff that nobody will ever be able to find out what it was good for.
This was fine when it was done, but it will not be fine for a high
quality "product". And with a userbase of 10mio we should aim at that.
