[PATCH] Merging identical changes from another branch
From: Michael A Fetterman <Michael.Fetterman@cl.cam.ac.uk>
The issue comes up when a local uncommitted *new* file (i.e. not in the
current manifest) is being merged with an identical file from a branch.
Since the file is not in the current manifest (it's either in the
current "to-be-added" list, or in the "unknown" state), there's no
(local) node from which to create a mergepoint.
