Not a proposal, just citing existing/common standard:

For what it's worth, my personal preference is around 64 columns
because I have a short attention span and bad eyesight.
However 80 columns is the common standard, so I manage with 80.

Longer format error messages are fine if it helps users find
errors with grep.  However, output of error messages should
still be wrapped at 80 for compatibility and readability.
