Use my script I sent to show that the conflict callback wasn't used
for property conflicts, then change it to first commit the property
change in wc2, then add another property on wc2\file to get the local
(sorry, don't have access to my script right now, since I'm in the
office and not at home)
But yes, I also discovered that the base path is always NULL (not set).
I've made TSVN just call the two-file diff in that case, showing
"theirs" and "mine". Not perfect, but it works.

Is it really necessary to create a new tmpfile somewhere? The
properties already are passed in temp files, so I (for now, depends on
your answer) just use the "mine" property temp file and write the
resolved stuff in there, then pass the path of that temp file back in
That should work too? Or do you need the temp files unchanged? It
won't be too much work to create a new, separate temp file to pass
back - I just used the fastest way.

For text conflicts I found that the "merged_file" is used when
'choose_merged' is passed back - no need to create a tmp file there.
