Oooh, right. Thanks for noticing. So I guess I should try to run it
instead. From the POSIX spec, I can't find a way of running it that
guarantees a return-code of 0 without clobbering the console somehow.
Perhaps the best thing is pass no operands, and check for $? == 127 instead?
Something like this?
diff --git a/t/test-lib.sh b/t/test-lib.sh
