Comment (by jstolarek):

 Copy-paste from ghc-devs (since Richard requested):

 Firstly, I hate explaining myself to Arcanist. When prompted to explain
 the reason for too long lines I typically enter "wontfix" without thinking
 too much.

 Secondly, I really don't like how warnings clutter code reviews.

 I have my Emacs highlight text beyond 80th column with a really ugly
 colour, so I strive real hard to maintain 80-column limit whenever
 possible. But sometimes fitting in that limit is nearly impossible:
 imagine being in a let nested in a do-notation nested in a guard nested in
 a where clause. Approx. 15-20 columns are lost for the indentation.
 Nevertheless I would support introducing a hard limit on having no more
 than 80 columns.
