I think the message was actually from a turn-key board manufacturer,
who will also buy the parts and stuff the board.  They apparently ran
a DRC as Dan did, before sending the Gerbers out for fab.  Since it's
not easy for PCB, they to agreed do the masking themselves.  I don't
fault them for noticing and asking me to do something about it.

I agree that a DRC for this in PCB would be nice (hmm, switchable,
default on, performed at the same time as the other DRCs).  Then I'd
take the time to fix all my footprints.  But that doesn't let Levente

do what he wants.
