	I'm all but done with the rc* files and moving on to the other
places in /etc that use test currently. There are 6 states that take 99%
of the cases into account:

yes no !yes !no presence-of-a-variable absence-of-a-variable

Frankly, I'm not sure what the proposed functions get us. Current tools
take all of those possible conditions into account, and adding custom
hacks for common cases will increase the likelihood of people writing
extremely non-portable scripts with them. Maybe I'm missing something
though...  Also, keep in mind that it's not just case sensitivity that
we're working with here. It's also the fact that case is a sh builtin, as
opposed to test which is not.
