        * lily/beam.cc lily/stem.cc lily/beam-engraver.cc allow for
        stemLeftBeamCount and stemRightBeamCount to equal 0.
        Fixes [c8 c4 c8]

        * lily/piano-pedal-engraver.cc Rewritten to support bracketed as2002-03-11  Jan Nieuwenhuizen  <janneke@gnu.org>

        * scm/grob-description.scm (Beam): Add concaveness.  Replace
        Beam::cancel_suspect_slope with Beam::check_concave.

        * lily/beam.cc (check_concave): Calculate concaveness of beam, and
        set slope to horizontal if concaveness > Beam.concaveness.  This
        handles cases that kludgy cancel_suspect_slope was meant to catch
        very well.
        (cancel_suspect_slope): Remove.

        * lily/grob.cc (warning): Use cause tracking to give more
        meaningful errors from the backend. 

        * lily/property-iterator.cc (check_grob): Warn if setting grob
        property in unknown grob. 

        * mf/feta-toevallig.mf: brushed stems for natural sign.

        * lily/molecule.cc (align_to): don't translate empty molecule.
        (this triggers a very subtle bug in time-signature.)  

2002-03-10  Han-Wen  <hanwen@cs.uu.nl>

        * lily/spring.cc: remove file.

        * input/regression/spacing-stem-bar.ly: new file

        * lily/score.cc (run_translator): resurrect point-and-click

        * input/baerenreiter-sarabande.ly: Copy Barenreiter beaming for
        sarabande layout

        * lily/spacing-spanner.cc (find_shortest): Shortest note for
        spacing is now globally determined, using the most common shortest
        note. Notes that are shorter are spaced geometrically, and with
        expand hints. This makes spacing more even, and measures that have
        very short notes won't be that stretched out.  

        * mf/feta-klef.mf: F-clef fixes, documentation on the
        shape. (WARNING: font changed.)

2002-03-09  Han-Wen  <hanwen@cs.uu.nl>

        stiff springs.

        prefatory matter is fixed.

2002-03-08  Han-Wen  <hanwen@cs.uu.nl>

        * lily/note-spacing.cc (stem_dir_correction): Correct spacing for
        barline following an upstem.

        * lily/staff-spacing.cc (extremal_break_aligned_grob): destill
        function from next_notes_correction().
        (bar_y_positions): idem.

2002-03-04  Han-Wen Nienhuys  <hanwen@cs.uu.nl>

        * input/regression/break.ly (texidoc): bugfix: escape \ in
        strings.

        * lily/staff-spacing.cc (next_notes_correction): Correct the
        spacing of a note following a barline.

        left-align molecule.
        
        * lily/break-align-interface.cc (do_alignment): completely
        rewritten. Now it does not use Align_interface anymore, but a
        separate routine. Like StaffSpacing, it reads space-alist from the
        breakable grobs.  This allows you to set spacing using
        
        \property Staff.Clef \override #'space-alist = '(....stuff....)  
 
        * lily/bar-line.cc, lily/include/bar-line.hh: change name from Bar

        * lily/spacing-spanner.cc: move from third-try.cc; rename
        Third_spacing_spanner to Spacing_spanner.

        * lily/staff-spacing.cc (get_spacing_params): redo prefatory
        spacing stuff. Much cleaner now, and we prepare for neat spacing
        tricks around bar lines and such.

        * lily/third-try.cc (prune_loose_colunms): bugfix. Don't init
        variables with themselves. (Ouch.)
