[OSM-dev] 7500 disfigured ways deleted

    when postprocessing OSM data, one often encounters ways that make no 
sense - ways with 0 nodes, ways with 1 node, or ways with 2 nodes where 
both nodes are the same (the same id, not the same coordinates).

I have deleted them from the database now (roughly 7500 ways affected). 
Some could not be deleted because they were incorporated in relations, 
in which case I didn't bother.

For details, see 

I have a script to revert the operation wholesale if it should turn out 
that there was a judgement error on my part and these ways indeed served 
a purpose.
