That's good to know.

I'll have to experiment to see if I can create a rejected file and how it
responds to see if it is easy to pick up on.

My only concern about this approach (and I considered it) is about losing
local modifications.  This whole process would be fairly trivial if I
didn't have to worry about that.  We need to do things at times in the
vendor-like area to stub out sections of code or put in some unique data
handlers and update some of the properties.  If I do a revert, I lose that
information.  An ignore properties merge that would show conflicts would
really scratch this itch.  I'm guessing I'll be stuck with the trip through
diff and patch.

Thanks,
Dan
