I basically got a little lazy and didn't copy the svn_client_copy3()
documentation. I plan on revisiting the documentation when we iron out
the atomicity rules (below).

I stole that from svn_client_copy3(). I haven't looked into exactly why
the copy functions need to use force.

All good questions. When performing a multiple local add, we keep
adding, even if we encounter an error with a previous file. I believe
my multiple move and copy implementation does the same thing, although
it needs be tested more thoroughly. ->repo operations are atomic.
I'll update the documentation to reflect the above, but I also wonder if
it is correct. What should the behavior be for a ->wc operation which
fails on some files but not all? Should `svn add' be modified to check
addability before performing the add and fail if some of the files can't
Whatever the answers are, we should be consistent across all svn
commands, not just `copy' and `move'.
