Re: does emacs wrap lines that are exactly 80 characters long??

[seberino@spawar.navy.mil (Christian Seberino)]

So if I understand you correctly, 80 char long lines WERE a problem
in 80 char long windows PRIOR TO VERSION 21  because of the slash at the end??

But, in current version of Emacs and beyond this is not a problem
anymore and I don't need to have <= 79 char wide l lines??
