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

[Simon Urbanek]

The build-in editor doesn't store any text attribute changes as the  
output is plain text. It does, however, allow text attribute changes,  
because they are used e.g. for syntax highlighting. Strictly speaking  
the bug is that you can use the <Cmd><U> command at all.

Another approach would be to enhance the editor to support RTF format  
(internally it actually does allow it) which would allow you to use  
formatted text and store it. The drawback is that such a text is no  
longer executable directly in R, so you couldn't "source" it. I not  
quite sure what is more useful - I'm almost inclined to think that  
banning text format changes makes more sense, but I'm open to other  
suggestions...

Cheers,
Simon
