Hi!
Here's my revised patch. I've commented on the changes inline.
One strange thing: If you compile this you'll get a compiler warning
about this variable not beeing used:
1354 apr_array_header_t *deleted_targets;
But if I remove it, no targets will be condensed. It's really silly. Can
someone explain why a variable that isn't used must be declared in order
for my code to work. What is the simple logical explanation?

I used svn_wc_walk_status() instead. It does not handle externals but
treats them as unversioned. No problemos for us, we just want to find
out if anything exists in a dir.

In my new patch I loop over the targets in the beginning and check for
targets to be deleted. If none, we're done and can return. Takes more
iterations but saves some memory.

Nope, it's needed. If we have a parent dir target, then it does not
contain any patch. When svn_diff__close_patch() tries to close the
streams we get a segfault.
