This is such a general problem that people bump into all the time that I
think Emacs should have an even more general solution, and it should be
on by default.

The long-file warning isn't sufficient -- there's plenty of smaller
files that have this problem, too.

Why doesn't Emacs just check for long lines (in the C code, for speed)
when opening files, and offer the "visit literally?" if it detects them?
