We use print_ver_ to run "PROG --version" for each program under test. Some tests have been derived from others, while the argument(s) to print_ver_ have not been adapted. Add a new cfg.mk rule to prohibit this. * cfg.mk (sc_prohibit_test_calls_print_ver_with_irrelevant_argument): New rule, to prohibit a test script from calling print_env_ for a program not actually used by that test. * tests/chown/basic: s/\(print_ver_\) chgrp/\1 chown/ * tests/cp/acl: s/\(print_ver_\) mv/\1 cp/ * tests/cp/capability: s/\(print_ver_\) ls/\1 cp/ * tests/cp/cp-parents: s/(print_ver_\) mv/\1 cp/ * tests/du/bind-mount-dir-cycle: s/(print_ver_\) rm/\1 du/ * tests/misc/wc-parallel: s/(print_ver_\) md5sum/\1 wc/
