[R-SIG-Mac] built-in editor underlining

[Parlamis Franklin]

Thanks, Simon.  Of course I don't think you should do anything that  
would prohibit sourcing the file (and I guess most would agree).

Re: syntax coloring.  I've turned it off because, when editing the  
beginning of a long file, I would get a long delay (multiple seconds)  
after I entered an open quotes (") as the rest of the document  
changed color because all quotes were now matched differently.  Not  
sure whether this is a slow implementation of that functionality, or  
what is to done about it, but for this user at least, the delay issue  
outweighs any benefit that I could get from syntax coloring.
