I am engraving an orchestral score, and ran into the following: one

and those notes are in separate files. Viola part should not be
aware of the alternative block in violin IMHO. So, how should I
write this piece to be correct? (online version: http://lilybin.com/mpasgy/4)
\version "2.18.2"
\language "deutsch"
violin = \relative c'' {
\repeat volta 2 { c4 d e f | }
\alternative {
{ c2 e | }
{ f2 g | }
}
c1
}
viola = \relative c' {
\repeat volta 2 { c4 d e f |
c2 c }
c1
}
\score {
<<
\new Staff \violin
\new Staff { \clef alto \viola }
>>
\layout { }
}
I believed I answered this already on the bugs list here:

I don't think you did. You claim there that "looking at it by the raw
musical content, I see 4 bars for violin and only 3 for viola", but
you don't explain why you see that as a problem. You are counting
notation, not actual bars as played. Why does it matter that, say,
ten played bars might be expressed as only five bars repeated? And
your expansion of the parts there is incorrect: you have included the
first time bar the second time around for the violin, suggesting six
bars played in total, whereas there are actually only five.
It got me thinking, though. Why don't you want the viola to have the
same \repeat volta 2 { ... } \alternative { { ... } { ... } }
structure, too? If you are making individual part scores, then
you're going to need it, IMHO.
That's your dispute with the original questioner, who prefers the
viola players not to see what is going on in other parts. (I happen
to agree with you: that it is clearer if the identical first and
second time bars in the viola part are laid out in the same way as in
other parts. I *think* (she doesn't say this explicitly) that Elaine
Gould agrees.)
If that's really not what you want, what should the viola be playing
during the violin's 2nd ending?
Oh, that's easy and evident: exactly what is written. The last
(second) bar of the viola part's repeat coincides with the second
time bar in the violin part.
