Not really relevant.

Several people gave reasons why they wanted to show invalid sensors.  I
think that at least some of those would have been happy with a '-a' or
'-v' option to list them.  It would be consistent with other utilities,
I think, to have a '-q' to suppress invalid sensors or a '-a' (all) or
'-v' (verbose) to list them.

It's reasonable to ask if others would like the same functionality and
not make any change that any random person requested.  However, a better
response might be: "Why do you think that this is something that would
be useful to more people?"

> 4- It has enough flags already.

Would it make the code more confusing?  That would be a reason (either
for not making the change or for refactoring the code some), but we
don't really have a limit on the number of flags we accept--at least
until we run out of symbols...

Not a reason.  But a nice sentiment.  :-)

I think the envsys2 changes are good, and the subsequent suggestions
make them better.
