In theory yes, but as I mentioned in my first message, it comes up
surprisingly often, at least to the degree that I think it would be
something nice to have in general.  If you think the current
implementation is too primitive, one could extend it to check if the
region is a subregion of a hunk, and handle that appropriately.
