bug#44858: [PATCH] Make byte-compiler warn about wide docstrings

[Drew Adams]

(FWIW, I'm not convinced this is very helpful.)

But if you do add this, please consider letting
the message provide the actual longest-line
length.

Someone concerned with fixing long doc-string
lines might be more concerned with fixing one
with, say, 179 chars than one with, say, 82.

Presumably the actual longest-line length is
available for the message.  Why not show it?

Or maybe not.  If your code finds only the
first line that's > 80 chars then it won't
help as much.  Doc strings are typically
fairly short.  Looking for the max line
length isn't very expensive.
