Is there a patch somewhere that will allow differentiation in 
syntax-coloring between strings and regular expressions in XEmacs? When 
I first experimented with Ruby, I seem to remember something of the sort 
with Emacs, but I'm using XEmacs now. With Ruby 1.6.8, strings and 
regular expressions were highlighted the same. I just switched to 
1.8.0pre3 at home, and now regular expressions aren't highlighted at all.
