Fixed.

I reworked those two paragraphs to incorporate those suggestions and 
hopefully clarify the idea bit further. (I'll revise these again once I 
support multiple WITHOUT OVERLAPS columns.)

I couldn't reproduce this. If you're still seeing a failure please let 
me know what you're seeing.

These patches also fix a problem I found with FKs when used with 
btree_gist. Privately I'm using the script below [1] to re-run all my 
tests with that extension and int+range columns. I'd like to add 
something similar to contrib/btree_gist. I'm open to advice how best to 
do that if anyone has any!
