[PATCH] Bug: failed octopus merge does not create MERGE_HEAD

[Michal Sojka <sojkam1@fel.cvut.cz>]

Hi,

the following test case exhibits behavior which I think is a bug. If
merge-one-file cannot handle the merge we end up with unmerged index
entries and no MERGE_HEAD created. I suppose that MERGE_HEAD should be
created whenever a merge fails.

If someone gives me a hint how to correct this, I can try to do it.
