My .vimrc only has my setting of textwidth to 0, but as you mentioned vimrc I have also set /etc/vimrc to tw=0 as well. We shall see what happens, unfortunately this change to my tw setting is a random (and relatively infrequent) event. Time will tell, I guess.

However, I do not expect it to solve the problem, as my .vimrc will follow /etc/vimrc, and the real problem is that some part of vim arbitrarily changes this setting. Most of the time I can change and create long lines without incident, because tw is 0. But sometimes it is 78.
