Ok, in the \footnote issue 2505 there is an example with a breath mark.
That looks something like
\breath c4\footnote #'BreathMark ...
for getting a footnote to the breathmark. Ugh. This could be done with
\breath <>\footnote #'BreathMark ...
but it would also be feasible to make a function taking _one_ postevent like
post = #(define-music-function (parser location ev) (post-event?) #{ <>$ev
#})
and say \breath \post\footnote #'...
In contrast to <>, it would only accept a single postevent. And I can't
think of a really good macro name. \now\footnote does not convey the
problem that there is only one postevent acceptable.
