* The "block_cache" command checked the wrong variable to see if a block

could be found or not, eventually resulting in a read fault.
* It now also uses parse_expression() for its second argument, since it
  now returns an uint64 in Haiku.
* Tracing output cut off the label too early.
* Minor cleanup.
