I have to say that merge conflicts are not very much fun. I tend to do a
certain amount of oh, take all the changes from the server.  I wonder if
the approach that someone else mentioned of keeping a file
tags/message-id with the appropriate tags in it might make merging less
painful.

Yeah, the footgun potential is definitely there.

Heh, I think I later posted a patch to do that as well.
