Pure serendipity. The basic mechanism used (the bit-mask) allowed
non-continguous masks as a natural consequence of the mechanism; we would
have had to specifically disallow them, and we didn't bother to. I seem to
recall we thought we'd leave them in, and see if people found some good use
for them.
