[R-SIG-Mac] "Extra" new line characters in history w/ R 2.9.1

[Jeffrey Carroll]

Hi All,


I recently upgraded to R 2.9.1 on my MacBook Pro running Mac OS X  
10.5.7.

Previously, at the command prompt in the GUI the up arrow key scrolled  
through the history.  This still works for me, but every time I scroll  
up the previous command gets an extra new line character appended to  
it.  I've attached a screen shot showing what happens when I  
repeatedly use a single stroke of the up arrow to recall the previous  
command.  This is trivial, but makes using the history rapidly more  
challenging because you have to delete though a bunch of whitespace  
when trying to edit previously used commands.

This changed immediately after I upgraded to 2.9.1.  Does anyone know  
if something in R/GUI changed, or if I just had a setting that I don't  
know about altered when I upgraded?


Thanks for your advice,


jeff
