It doesn't really matter where it came from, what matters is whether
people still commonly use 80-column windows or not.

I know people that only ever use one (huuuge) full-screen editor window
with small fonts, and can happily view lines that are 300 characters
long (of course, the right 80% of that window is almost always
completely blank...).

In my case, I use 80-column windows because (1) it allows me to have two
editor/terminal windows side-by-side with a reasonable font-size on a
typical display, (2) it reduces the amount of wasted blank space in
editor/terminal windows that you'd have if you made your windows really
wide just for the very occasional wide line, and (3) it's, well,
standard, or at least as much of a standard as we have, which is useful
when interacting with other people.

Anyway, I think the vague consensus seems to be that it's OK to go over
80 chars in many cases, but that it may be an indicator that some
refactoring is in order....
