Positioning segno and coda (with line break)

If you want to place an exiting segno sign and add text like “D.S. al Coda” next to it where usually the staff lines are you can use this snippet. The coda will resume in a new line. There is a variation documented in this snippet, where the coda will remain on the same line.

%% Warning: \fine no longer enforces the end of the music.  If your piece
%% has music following \fine that you want to exclude when it is
%% unfolded, use \volta to exclude it.
%% Please refer to the manual for details, and update manually."

%% Alas, the use of \fine here is not problematic here --harm
