WPCS 1.0.0 includes a bunch of new auto-fixers, which drops the number of coding standards issues across WordPress significantly. Prior to running the auto-fixers, there were 15,312 issues detected. With this commit, we now drop to 4,769 issues. This change includes three notable additions: - Multiline function calls must now put each parameter on a new line. - Auto-formatting files is now part of the `grunt precommit` script. - Auto-fixable coding standards issues will now cause Travis failures. Fixes #44600. Built from https://develop.svn.wordpress.org/trunk@43571 git-svn-id: http://core.svn.wordpress.org/trunk@43400 1a063a9b-81f0-0310-95a4-ce76da25c4cd
