Code is Poetry.

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
