  SVN rev 190494 on 2009-03-28 06:47:05Z by delphij
  
   - If (keysize+datasize)%(bsize=14)==0, insertion of a `big key' would cause
     an invariant (actually, an ugly hack) to fail, and all Hell would break
     loose.
  
     When deleting a big key, the offset of an empty page should be bsize, not
     bsize-1; otherwise an insertion into the empty page will cause the new key to
     be elongated by 1 byte.
  
     Make the packing more dense in a couple of cases.
  
   - fix NULL dereference exposed on big bsize values;
