partcombine: "Solo II" or "solo II" or "solo2" or...

[Dmytro O. Redchuk]

Hi, masters!

The docs [1] says:

«In solo situations, the first and second parts get marked with ‘Solo’
and ‘Solo II’, respectively. The unisono (a due) parts are marked by
default with the text “a2”.»

[Note different quotes, btw: ‘Solo’ and ‘Solo II’ and “a2”.]


But, on the other hand, one of regtests [2] says [3]:

% ...
comm = { s1 s2 s4_\markup { \small "expect: solo 2" }
% ...

After some browsing (sorry, not too aggressive) i've found (in different
random places) "solo" (lowercase "s") and "solo 2", so... [4]

Please, if anyone have a solid reference --- what really *should* be
there? Which text?

A lot of thanks!
