+. *In Caro Mio Ben, bar 8, there's a syllable that starts on a note, and
ends on a pair of grace notes. Standard practice is to mark this with
a slur starting on the main note and ending on the grace note, so a
singer knows where to break the words.
-In bar 26, there's a \p marker that should appear below the grace
-note.
-
In bar 27, there's a crescendo that's supposed to start at the start
of the grace notes and extend to the note after the grace notes.

-How do I specify these?

this is a similar problem (if not another symptom of the same problem) as
one of the spacing bugs mentioned in the TODO.

The words are aligned with the main note, not the start of the
grace note. This is usually wrong, but is sometimes right.

+. * It is impossible to typeset two textual scripts that are stacked
on top of eachother and avoids note collisions and at the same
time are typeset with different textStyle. I tried to move around
the text_engraver and other engravers between Voice and Thread
be stacked vertically, avoiding collisions with the notes
in all voices.
