Hmm. It looks like threeway_merge is getting bogus input. In a regular
merge (e.g., branch changes file "file", master adds new file "other",
branch merges master), threeway merge sees:

  - call 1: index=file, head=file, remote=file
  - call 2: index=NULL, head=NULL, remote=other

But if the change to file is a D/F conflict (as in the scenario John
described), we get:

  - call 1: index=files, head=files, remote=""
  - call 2: index=files.upstream/delete.me, head=NULL, remote=NULL

and it barfs because index != head in the second call. But the "" entry
in the first call makes me wonder if this is the same "lists getting out
of sync" problem as before.

This is as far as I got.  I don't have any more time to look at it
tonight, unfortunately.
