git-merge expects this check to be done appropriately by the
merge strategy backends. In the case of merge-ours strategy,
the resulting tree comes what we have in the index file, so it
must match the current HEAD; otherwise it would not be "ours"
merge.

This adds the coolest merge strategy ever, "ours". It can take
arbitrary number of foreign heads and merge them into the
current branch, with the resulting tree always taken from our
branch head, hence its name.
What this means is that you can declare that the current branch
supersedes the development histories of other branches using
this merge strategy.
