Apply Layout/RedundantLineBreak rule to short lines

We're not adding the rule because it would apply the current line length
rule of 110 characters per line. We still haven't decided whether we'll
keep that rule or make lines shorter so they're easier to read,
particularly when vertically splitting the editor window.

So, for now, I'm applying the rule to lines which are about 90
characters long.
