StableCommentWhitespaceTest.php
Tests the comment tokenization.
Comment have their own tokenization in PHPCS anyhow, including the PHPCS annotations. However, as of PHP 8, the PHP native comment tokenization has changed. Natively T_COMMENT tokens will no longer include a trailing newline. PHPCS "forward-fills" the original tokenization to PHP 8. This test file safeguards that.
