Merge Conflict Resolution - local add, incoming add upon merge

We have a couple scenarios that seem to cause merge conflicts when merging
branch data back to the trunk. This is despite the user selecting
--accept=theirs-full in the merge operation.

The two scenarios are:
1) A file that was branched from the trunk is now deleted in the trunk and
now is being attempt to be merged back from the branch. If no changes are
made on the file in the branch you get nothing conflicted or brought in all!

That's as expected. (Julian Foad)

If there are changes (file or properties) it conflicts with status of
> "local missing, incoming edit upon merge" but you can't do any sort of
> resolve to pull in the branch version (only working state which means
> doesn't exist).

Unfortunately that's a limitation of tree conflict resolving at the moment:
such an option has not yet been written. (Julian Foad)

 2) A file of the same name was created on the trunk and branch AFTER the

We agree it should work, the support for doing it just hasn't been
implemented yet. (Julian Foad)
