Yeah, I had a similar thought, but it just feels so hacky. Is there
anything wrong with making this completely separate from the content
update. I.e., just applying the pathspec to the index as a separate step
and adding "+x" to each entry?

This really is just a more convenient interface around "update-index
--chmod", isn't it? We should be able to do the same thing it does.

Sure, the simplest and the most straight-forward way may look dumb,
but it would be the safest.
