Reply-To: Bug reports for Aquamacs Emacs <aquamacs-bugs@aquamacs.org>

There is a problem with the redisplay in recenter-top-bottom. Place the cursor 
at the beginning of the 2nd line of the 4th paragraph of the following text. 
Type C-L to cycle through the recenter positions. When that line is placed at 
the top of the screen, additional words from the previous line appear inserted 
at the beginning of the line with the point.

Sample text file (between lines of ='s)
