I think the key line in Jim's document is:

   Since all merging takes place on the client, these "smart merges"
   should be implemented as a client-side plug-in.

So the problem is to identify the ways in which our current plugin
mechanism is not sufficient (which is probably related to Garrett's
statement about --diff-cmd and --diff3-cmd being "half-assed"), and
improve it. That's all that should happen in Subversion itself, IMHO.
The actual implementation of the merge methods should happen
externally.

There have been some recent threads on the problems of --diff-cmd,
--diff3-cmd, and Subversion's [mis]interpretation of svn:mime-type. I
don't have the thread URLs handy (sorry), but I think the place to
start would be there, to see what, if anything, has already been
analyzed.

Best,
-Karl
