[PATCH v2] Improve diff pattern for PHP files

["Javier Spagnoletti via GitGitGadget" <gitgitgadget@xxxxxxxxx>]

From: Javier Spagnoletti <phansys@xxxxxxxxx>

PHP allows some function modifiers that are not recognized in our current hunk header pattern

       final public function foo() { }
       abstract protected function bar() { }

Add "final" and "abstract" to the list of function modifiers.
