tests: use compare-vs-/dev/null instead of 'test -s'
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.
