The immediate fix is attached. It's rather trivial. 8=] Also of note is
that it fixes the Python test I was struggling with.

[[[
Create proper wrapper functions for svn_wc_diff_callbacks3_t and use them.
Also change the misleading comments on the old wrappers.

* subversion/libsvn_wc/deprecated.c
   (file_changed, file_deleted, dir_deleted, dir_props_changed, dir_opened,
dir_closed): Relabel as svn_wc_diff_callbacks3_t functions, since that's
what they're used as.
   (file_changed3, file_deleted3, dir_deleted3, dir_props_changed3,
dir_opened2, dir_closed2): New functions.
   (callbacks3_wrapper): Use the new functions above.

I'd also post a patch renaming the wrappers to something more telling — if
someone approves.
