My thinking on this is to just not break the file-format anymore
until we switch to an extensible one. At that point we'll write
an importer and exporter to the old format -- and this exporter's
output could work with pcb versions back to 2007 (or earlier) just
as pcb does now.

Perhaps the new file format is too far away. (I for one won't
have time to do such a thing until next summer.) But it would be
nice if our current .pcb parser had no more cruft to deal with.
