Looks fine, but I thought you wanted to use only one of outside-staff-horizontal-padding or skyline-horizontal-padding I need to be clear on this because I'm implementing \markLengthOn and the analogous \textLengthOn needed to remove these paddings. https://codereview.appspot.com/8632044/diff/1/scm/define-grobs.scm File scm/define-grobs.scm (right): https://codereview.appspot.com/8632044/diff/1/scm/define-grobs.scm#newcode1419 scm/define-grobs.scm:1419: (outside-staff-horizontal-padding . 0.12) So, padding is 0.32 if the mark is outside the staff ?
