WordPress' code just... wasn't. This is now dealt with. Props jrf, pento, netweb, GaryJ, jdgrimes, westonruter, Greg Sherwood from PHPCS, and everyone who's ever contributed to WPCS and PHPCS. Fixes #41057. git-svn-id: https://develop.svn.wordpress.org/trunk@42343 602fd350-edb4-49c9-b593-d223f7449a82
