Two problems: font choice and lyrics

[simon_albrecht]

Hello everybody,

during my recent work with lilypond I encountered two quite annoying
problems:
- If both fontsize and the font itself have been changed in a document,
the font choice is not taken into account and Computer Modern appears
nevertheless. Omitting the change of fontsize also rids the problem.
- inside a StaffGroup, \addlyrics doesn't recognize the voice I ask it to,
if there is another (silent) voice (which, in the real-life example, I
have only inserted in order to allow line breaks in the middle of
measures) in the same staff. If I try the same without a StaffGroup,
another - maybe related - error occurs: the "\new Lyrics" command doesn't
work although it is in the usual place, I think.

The appendix contains an example, which I thought minimal, for each of the
three cases.
I sincerely hope there no tiny mistakes in use which I overlooked, and
that you can find a solution.

Thank you all very much for providing this excellent (if also
time-consuming) alternative to so much music typesetting available, which
is between bad-looking and outright awful!
Best regards

Simon Albrecht
