Depends on your definition of right.  The purpose is to be able to use the 
scrollbar to get the last line to the top of the window.  Gedit can't do that. 
 This is an Emacs convention, but as said, hard to implement right with 
current toolkits.

But AFAIK, only Emacs does this so most users are surprised.  Maybe we should 
make this customizable.
