Comment (by mf2k):

 Please go ahead and make the patch name changes.

 I don't think either method is preferred. I don't believe that everyone
 (like me) regularly checks pulls requests. But there may well be Macports
 developers who do check that more often than tickets. So do what is
 easiest for you.
