And I raised a brow when reading that.  "Restore" is a very far cry
from "fullscreen".  OTOH, browsers that keep history use "restore", so
I thought it will be a better terminology here.

The difference is that "undo" is widely accepted terminology for what
that does.

But undelete-frame (the command) is NOT the opposite of delete-frame,
because it doesn't just delete the last frame you deleted.

Anyway, I don't intend to argue more; if you are unhappy with my
proposal, so be it.
