*Bonk*  Scott, thanks for making me realize that I was barking up the 
wrong tree.  I was using preg_split() instead of 
preg_match_all().  preg_split() finds delimiters and preg_match_all() 
finds the words themselves.

Both your and my regular expressions work with preg_match_all():

http://juniperwebcraft.com/test/preg_split_Novitski01.php

but not with preg_split().  My own RegExp gives at least a partial 
result with preg_split() but that's probably coincidence; I need to 
start from scratch.

Regards,
Paul
