[PSR-12] Line-length enforcement

[Chris Emerson]

Hi all,

First of all, I know that it is specifically stated as a non-goal of this PSR to change anything in PSR-2. However, I think this statement is a mistake, and since PSR-2 is accepted and cannot be modified, this is the place to do it.

I and my colleagues don't think it should be the place of this PSR to dictate how the standards within it are enforced - only to define those standards. We believe that outputting warnings for items which aren't fully enforced is harmful, in that it creates noise amongst the real errors and warnings, and trains people to ignore warnings when they occur.

I have opened a pull request at https://github.com/php-fig/fig-standards/pull/993 to amend this part of the PSR, but I'm unsure if it's been discussed before (I couldn't find anything) or what the opinion of others is, so hope to start a discussion while it is still in the review phase.

Thanks,

Chris

Looks like a good change. PSR except, maybe, meta should not dictate on how exactly to achieve its goals.
