[Rune Zedeler]

Does this look ok?

2002-09-05  Rune Zedeler  <address@hidden>

        * scm/output-lib.scm (make-molecule-boxer): Fixed and moved from
        input/test/boxed-molecule.ly

        * input/test/boxed-molecule.ly: Fixed to use default
        make-molecule-boxer

        * input/test/bar-number-every-fifth.ly: Added
        
        * lily/bar-number-engraver.cc: Add grob-property
        bar-number-visibility and use it to decide which BarNumbers to
        suicide.
