Edit Question
Title
Body
I don't understand this part of php's PSR-2 convention: The soft limit on line length MUST be 120 characters; automated style checkers MUST warn but MUST NOT error at the soft limit. Lines SHOULD NOT be longer than 80 characters; lines longer than that SHOULD be split into multiple subsequent lines of no more than 80 characters each. I thought "soft limit" meant "try to stick to this limit, but a few characters extra are not a problem" . But then I read the second line and now I don't get it.
