REVISION SUMMARY
  The pretty printers already had a pretty approach for empty
  containers, these got an 'empty ' prepended to their output.
  But when you are printing large containers, how do you know the
  size of the container? Often, it's not straight forward to get
  to the size, e.g. for a QList. To help the user of the debugger,
  always append '(size = N)' to the output, which works for all
  situations. Remove the empty prefix, which is now obsolete.
