I am making a tweak to rc: if rc is invoked with any of the three
usual file descriptors (0, 1, 2) closed, rc will open /dev/null on
that descriptor.
I'm just checking to see that I'm not making a big gaffe here---I
want to avoid the nastiness that arises when Unix utilities are
called with any of those 3 descriptors closed. (also knowing that
0, 1, 2 are always valid fd's simplifies the bookkeeping inside
rc, but that is of secondary importance)
