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

[Parlamis Franklin]

if i open a blank document in the built-in editor and enter the  
following text:

Help

Help

and then underline the first "Help" (by highlighting it, and using  
either Meta-U  or Format>Font>Underline), the underlining will show  
up in my current session.  but if i save the document and reopen it,  
the underlining will be gone.  what is more, if i then open the  
document in another text editor (try TextEdit), highlight the first  
help and try to underline it, everything in the document will be  
underlined, including the second "Help"

i've been using 2.4.0 alpha (about a week old) and the R.app  
deployment build (Version 1.17-pre (3779)) for R 2.4.x from http:// 
cran.cnr.berkeley.edu/
