The Subversion API svn_client_move() (or svn_client_copy()) take a
source path and a destination path as arguments (among others). Now if I
want to copy
TSVN doesn't check every subfolder and if it might already exist in the
target. Subversion on the other hand does (if not, then please correct
me and explain why the different behaviour if the target already
exists), and it wouldn't take a whole lot more time for Subversion to
throw an error. If TSVN would have to throw an error, then it would have
to scan both subtrees completely before calling svn_client_move(). So to
make TSVN error out, each move would take twice the time it does now -
not a very nice workaround, especially since moving a lot of files in a
working copy already is very slow and consumes a lot of memory.

I'm not really interested that Subversion would merge those two
identically named folders, I just want it to throw an error in such a
case: that would be enough.
