Fermata on final barlines?

[Albert Frantz]

Hello,

I'm trying to get fermati on final barlines (2.8.2) using the code:

\mark \markup { \musicglyph #"scripts.ufermata" }

I've noticed that this code works only when preceded by a note; rests beforehand
do not work at all.

Also, the code doesn't seem to permit a fermata on the final barline of a piece.
 Am I missing something or have I uncovered a bug?


Thanks,

Albert
