AnotherTest 86f50aa74e Shell: Make tests use PASS/FAIL instead of exit codes
There's no guarantee that the last executed command will have a zero
exit code, and so the shell exit code may or may not be zero, even if
all the tests pass.
Also changes the `test || echo fail && exit` to
`if not test { echo fail && exit }`, since that's nicer-looking.
