Comment 4 for bug 1577368

Yes this bug is actually related to those cited, but on the opposite end.

I want to be able to disable the terminal size settings detection, and yes --max-width can help with that.

But it would even be better if an environment variable could do the same, so that I can set it only once per session's needs, and make that hidden from the view of my students, to avoid polluting the already steep learning curve with cosmetic options.
