test: exit on '-1' test non-zero status.

If a '-1' test program returns a non-zero status, don't go further and
compare it's (numeric) output values. This allows a '-1' test to
indicate a "skip" status or an otherwise error. (Currently no such '-1'
test would skip like this, though.)

Shell syntax note: `set -e` will not exit with the syntax like this
`test $(false) = $(false);`. The exit statuses of `false` in the
example will be ignored instead. But putting the output in a variable,
such as `VAR=$(false)`, DOES exit.
