When some program produces unexpected output, that use of compare-vs-/dev/null will ensure that the surprising output is printed in the test's output. With "test -s err" only, one would have to instrument and rerun in order to see the offending output. * cfg.mk (sc_prohibit_and_fail_1): Exempt 'compare' from this check. * tests/dd/misc.sh: Change "tests -s ... || fail=1" to "compare /dev/null ... && fail=1". * tests/misc/nice.sh: Likewise. * tests/rm/read-only.sh: Likewise. * tests/tail-2/inotify-race.sh: Likewise. * tests/touch/no-dereference.sh: Likewise.
