 `path_is_absolute()` utilizes `preg_match()` to check if the first
 character of a path string is either of two possibilities.  This is way
 overkill for such a simple case.  The alternative I've proposed via the
 attached patch is more performant and makes the intention of the code
 clearer (rather than obscured in a regular expression).
