I have committed 0002 and a different implementation of 0001. I set the
maximum line length to 95, which is the current maximum in use.
I'm open to discussing other line lengths, but
1) If we make it longer, then we should also adjust the existing
wrapping so that we don't have a mix of lines wrapped at 80 and some
significantly longer lines.
2) There are some general readability guidelines that suggest like 66 or
72 characters per line. If you take that and add the option name itself
and some indentation, then around 90 does seem like a sensible limit.
3) The examples from other tools posted earlier don't convince me. Some
of their --help outputs look like junk and poorly taken care of.
So I think nudging people to aim for 80..95 seems like a good target
right now. But I'm not against adjustments.
