An earlier commit a9cb3c6e changed git-commit to use the
contents of MERGE_MSG even when we do not have MERGE_HEAD (the
rationale is in its log message).
However, the change tricks the following sequence to include a
merge message in a completely unrelated commit:
$ git pull somewhere
: oops, the conflicts are too much. forget it.
$ git reset --hard
: work work work
$ git commit
To fix this confusion, this patch makes "git reset" to remove
the leftover MERGE_MSG that was prepared when the user abandoned
the merge.
