test-subrepo-recursion: deleted default arguments

Deleted default arguments from test-sub-repo-recursion. Rationale is
that it is confusing to read, when the arguments aren't at each
command in the test

#!/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)
