Err, actually "index_only". Since that's no_wd. But yea, you are
right, I didn't consider the index_only mode of operation here.

Remove uncontested renamed files during merge.
Prior to 65ac6e9c3f47807cb603af07a6a9e1a43bc119ae we deleted a file
from the working directory during a merge if the file existed before
the merge started but was renamed by the branch being merged in.
This broke in 65ac63 as git-merge-recursive did not actually update
the working directory on an uncontested rename.
