My first reaction was that it would be confusing.  We'd have a variable
to hold the threshold, and it would always show up in "show" or "help"
output, but most of the time its value would be ignored.  The trickier
something is to document accurately, the more likely it is to confuse
users.

I'm not real attached to either one.  If you think two separate knobs
is simpler, then that's fine with me.
