I think you would still get a property conflict and those are handled kind
of "oddly". It would be difficult to auto-resolve because there could be

Not sure, but I was thinking an MD5 hash would also work. I have not done
much with them, if I generate one in Java and someone else in C do we get
the same value?

I was thinking it could be useful to know they specified HEAD for when you
re-populate the dialog. If you specified HEAD last time, there is a good
chance you will the next time. Especially when merging between different
URL's. Either way you would have to determine the value of HEAD, and that
is the complicator.

That is not the issue. The property change would commit with the merge,
it is just that the commit will often fail because the folder with the
property change is out of date. When you are just doing a merge, as long
as the merged files are up to date you can still do the commit. I am not
sure this would be a big problem, it is just a slightly-icky side-effect.
I do think there are a lot of advantages to using properties.
