Ooops, ignore my other suggestion! If you just change the one line
like I said, it will not output suffixes, so pcb will save in mm but
read in cmils!

IIRC, 20100929 can read units suffixed with "mm" or "mil". We may
want to check on this and use suffixed units as appropriate, rather
than keeping in the "unsuffixed cmils" tradition.
