Attached is a (hopefully) safer version of my change to 'delete-frame'. 
In this patch, a hook can only cancel frame deletion if FORCE is 
non-nil. This way, if there were ever some bug with a hook, you (or some 
code) can still force-delete the frame.

This would probably still need a NEWS entry, but I'm personally less 
worried about this change compared to my previous revision. What do you 
think?
