You are right -- I just figured out how to make the via connect to the
surrounding plane easily:  hit Shift-k many times until no clearance is
visible around the copper annulus. (Verify using Ctrl-r, make sure
"Clearance width in polygons" = 0.)

I failed to set the clearance to zero at first, because I was using
ChangeClearSize(selected, 0, mil) and this appears to have no effect.
I usually avoid the increase/decrease keys because I generally want to
specify exact numbers, but it's fine to execute
"while (clear!=0) {Shift-k; }" manually whenever I need to do this.

Colin
