By the way, Marcus: there's no difference between a move and a copy; in
Subversion's eyes, a 'move' == 'copy + rm'. So whenever you run 'svn
log -v' and see something about a copy, it could be a move or a copy.

Right. This is the infamous 'repeated merge' problem that CVS
suffers, and is discussed in the subversion Design document. We'll
probably end up solving this problem by using properties. That is,
whenever you run 'svn merge', the files which get patched also get
some kind of information added to special "merge properties". From
then on, Subversion looks at these props to "remember" which changes
were merged on each file.
