Undo whitespace effects when changing coding style

GitHub-Issue: 53

Should fix the issue & another minor issue where `before-save-hook`'s non buffer-local value was modified.

2 unexpected fails happen when I run the tests, however this happens on the main branch too, without any of my modifications so I doubt that I caused it.  The failing test are: `php-mode-test-issue-124` & `php-mode-test-issue-136`.
