And of course with non-broken probes, "-v" would also help to see exactly
when the probe is run, using which commands, and what output they
produced. E.g., for SYMLINKS, we should probably drop the stderr
redirection from the probe so we can see how "ln" complains.

It might also be worth doing a "say >&3" at the end of the check, too,
to tell "-v" users the outcome.

Here is an updated version of my suggestion that does both of those
things.  I think it should just be squashed into your patch.

Thanks. The changes look good.
