the relations and ways with missing members and nodes are inconsistent
and don't make sense anyway. of the two approaches to restoring
consistency (a person reviewing them, or an automated process for
deleting them) i prefer the latter. other tools (relation checker,
etc...) should flag up any higher level breakage (routes missing
segments) which can then be reviewed.

what is a "keyboardl/chair filter"?

this problem (barring implementation bugs) will be fixed in 0.6, which
is just 3 short weeks away :-)
