After checking the issue it do seems that:
1) SVN Kit 1.8.11 implements the functionality differently than JavaHL 
in regards to the paths reported. And it seems to be the SVN Kit's bug, 
since both libraries should implement SVN API the same way.
2) SVN Kit 1.7.14 does not provide support for working copy-to-URL 
comparison. So, the patch would not work with SVN Kit 1.7.14 at all. I 
can't check with JavaHL 1.7.x now since it's troublesome in my 
configuration, but I guess it'll be the same anyway, because the error 
message I've got said something like "diff summarize could be performed 
only on the URL-to-URL basis".

So, I guess there is no choice but to make the code compatible with the 
SVN 1.8 only, since providing a wrong compare result is worse than 
providing nothing at all (on the other hand the functionality will 
completely stop working with SVN 1.7)? Also I suppose, the behaviour of 
SVN Kit connector could be adapted to its incorrect implementation, so 
that it won't seem different with JavaHL (though it does not mean the 
issue won't be reported to SVN Kit team).

Do you agree with the proposed solution or do you have any suggestions 
on the matter (as for example to leave the way to use the earlier 
implementation in case of SVN 1.7 connector is used)?
