I've just spent a couple of days with Paul and Mike and although we weren't
specifically discussing tree conflicts I've gained a much better general
understanding of how merging works in Subversion. I think I can now see how
far we have to take this conflict detection, and it's not too far.

Just a brief note on the rest of your questions: I'm not right back into this
in detail, but yes I think Nico was right on simplifying that case. On the
subject of renames, yes I think we can and should proceed with detecting
conflicts to the same degree (or lack) of sophistication that "svn merge"
already does (or doesn't) cope. I think this is feasible and useful.
