[Bug: 21.5-b16] make-overlay bug

Monday, 8 December 2003

        Dear Bug Team!

This is another bug reported on comp.emacs.xemacs by Phillip Lord.  He
says:

...
 (make-overlay 0 0) succeeds on emacs, and errors on xemacs. 

 I believe overlays on xemacs are just an emulation layer over
 extents? So this probably is a bug, as the emulation should be
 exact. Again its very easy to work around, and just a problem because
 I wasn't aware of it.  
This appears to be because make-overlay is a wrapper around make-extent,
and make-extent throws args-out-of-range with two zero arguments.
