Can you confirm that the bug in squizlabs/PHP_CodeSniffer#1218 does not appear on your branch?

[cweagans]

I can confirm that the code added by the commits in that issue are present in RC2, which is what composer installed for me. Since that's what Travis installed (https://travis-ci.org/felixfbecker/php-language-server/builds/197497074#L293), I think it's good.

[cweagans]

I can also confirm that the tests run successfully locally.
