Thank you for your reply.  My apologies about the formatting.  I noticed that 
the code appeared scrambled and quickly sent a follow-up to correct that.  I'm 
sorry you didn't see that and had to correct it manually!

Unfortunately, your suggestion produces the same jumping behavior.  I believe 
this is because it relies on comment-region which is also called by 
comment-line (comment-line does basically the exact same thing you suggest).  
It looks like the behavior occurs somewhere within comment-region-default-1 .  

I'm surprised to hear that comment-line, and that the my-comment-line, function 
do not produce the jumping behavior.  When I asked on emacs.stackexchange, it 
was verified by another.  I have reproduced the behavior with emacs --no-init 
on both Windows (GNU Emacs 27.1 (build (1, x86_64-mingw32) of 2020-08-21
) and GNU Guix (GNU Emacs 27.2 (build 1, x86_64-pc-linux-gnu, GTK+ Version 
3.24.24, cairo version 1.16.0).
 Are you executing it with org-mode enabled?  (I failed to mention that in my 
original email and specified it in my follow up.  Please excuse me!)

What version of Emacs are you using?
