I'm sorry but I can't reproduce this. When I'm editing a previous  
command and press <up>, no line is added and the just edited change  
is discarded (to be precise pressing <up> in the middle of a command  
moves your cursor up such that you can copy/paste in the history text  
- if you want the previous command, you have to go to the beginning  
or end of the line - but neither has anything to do with adding lines).

This is R  2.4.0 GUI 1.17 (3868), Mac OS X 10.4.7 ppc. What system  
and R are you running?

Cheers,
