graphlog: fix --follow-first --rev combinations

This solves a similar problem than the previous --follow/--rev patch. This time
we need changelog.ancestors()/descendants() filtering on first parent.
Duplicating the code looked better than introducing keyword arguments. Besides,
the ancestors() version was already implemented in follow() revset.

#!/usr/bin/env python

import errno, os, sys

for f in sys.argv[1:]:
    try:
        print f, '->', os.readlink(f)
    except OSError, err:
        if err.errno != errno.EINVAL:
            raise
        print f, 'not a symlink'

sys.exit(0)
