Letter case, the underline's shape and colour, a double strikethrough and a
freely raised run all had no home in the model, so every one of them was
dropped on import. They ride the marks now, render in CSS, and round-trip.
odf-kit's run formatting has a field for none of them, so a sentinel folds
them into the run's own automatic style — the route the character styles
already take, and it reaches every path odf-kit serializes.
