Missing sign-off? I saw it's missing in the other patches as well.

A minor change in behaviour here is that we are removing the temporary
index file unconditionally here, while we would previously only remove
it if both 'read-tree' and 'checkout-index' would succeed.
I don't think that's a bad thing, we probably don't want users to try
and use that index file in any way, and I doubt that's part of anyones
workflow, so I think cleaning it up makes sense.

Minor nit: I think the above should be 'fprintf_ln(stderr, ...)' to
match what we currently have.
