The result is a copy and paste from 2 .ly. The little up-right staff uses: #(set-global-staff-size 11) ; the rest uses: #(set-global-staff-size 20) . The command: #(layout-set-staff-size 11)
in the \layout section gives a not valid result. Are there same (scheduled) enhancements since http://thread.gmane.org/gmane.comp.gnu.lilypond.general/66291 ?
