Hi Reinhold,
There's a problem using tempoHideNote if there's no markup text, since
it returns SCM_BOOL_F to the engraver, resulting in a programming
error:
\set Score.tempoHideNote = ##t
\tempo 4 = 60
returns `Object is not a markup.'
I've attached a patch which gets rid of the error message, but I'm not
sure whether it's the best method method for fixing this. What do you
think?
Incidentally, I wonder whether ly:context-property should have the
option of returning a default, like ly:grob-property...
Cheers,
Neil

Subject: [PATCH] Ensure format-metronome-markup always returns markup.
- if tempoHideNote = ##t and there's no tempo string or markup, return
\null.
