[PATCH] read-tree: loosen too strict index requirements
This patch teaches read-tree 3-way merge that, when only "the other tree" changed a path, and if the index file already has the same change, we are not in a situation that would clobber the index and the work tree, and lets the merge succeed; this is case #14ALT in t1000 test. It does not change the result of the merge, but prevents it from failing when it does not have to. Signed-off-by: Junio C Hamano <> Signed-off-by: Linus Torvalds <>
