Looking at the stack of patches in git, it would appear that the
"before_pours" branch also adds the "keepout" or anti-polygon feature. I
overloaded one of the flags, and if that is set on a polygon, it cuts
away any touching polygons to leave a cleared area.

IIRC, "J" or the actions to change the (non-existent) "join" flag will
toggle the behaviour. The underlying flag is actually the negation of
"CLEARLINEFLAG". That flag on a line cuts polygons (IIRC), and now, if
it is applied to a polygon, _that polygon_ clears other polygons.

Yes, the flag naming is really confusing.. I perhaps could/should have
made up a new flag just for that purpose.

There is no guarantee this feature will make it back to main-line, and
even less so that its implementation / invocation details will remain
the same.
