I whacked this around some more, added basic docs, and committed it.

I took that out; "works on the two cases I tried" does not mean "portable".
It's possible we could do something involving having configure check for
rl_clear_screen() etc, but that seems like more work than is justified,
not to mention that the results would then be platform-dependent
*by design*. Frankly I kinda prefer the behavior without a screen clear
anyway; though this may just prove that I'm not accustomed to using the
original "watch". Anyway, that's open to a followup patch if anybody is
sufficiently set on doing it differently.
