Issues with checks of .h files

[byhlel]

1) Seems to be an issue with the include priority

The alphabetical order of includes doesn't seem to be properly checked.

Tested file:

#include <z.h>
#include <x.h>
#include <a.h>

Maybe it is not intended to do so but that's what I expected of:

include_priority(index, file, line_number, filename):

2) Seems to be an issue with the endif include guards

We end up entering the if check thus causing an error

#ifndef TEST_H
#define TEST_H

#include <z.h>
#include <x.h>
#include <a.h>

#endif

3) Seems to be an issue with the /* */ at end of .h file

#ifndef TEST_H
#define TEST_H

#include <z.h>
#include <x.h>
#include <a.h>

#endif /* ! TEST_H */

May be other issues as I tested those when implementing counting of functions.
