I'm trying to write some editorial notes for a score, and would like to have the references in uneven-width word-wrapped columns. The effect I want is something like:
Bar 27 This text is hopelessly garbled in the sources, which are also mutually
inconsistent. The editor has produced what he hopes is a performable
version.
Bar 28 "in tempo" aligned but probably best on 6/16 (in neither of the primary
sources
As fas as I can see, neither \markup nor \markuptext have this facility.
