Hi David,

Could you add a test case for whatever bug is being fixed here?

I'm a little concerned about giving the user a tuning knob which appears
to have a somewhat arbitrary default, and also without providing much
guidance to the user on how to set that particular knob.

I'd feel better if the code could somehow "know" when it needs to stop
tidying well enough that we would feel fine just not offering the knob
at all.

Thanks,

-Carl
