Original post:
-------------------------

> I'm not top posting.
% Ambitus is not correct in the case of:
% Manually defined clefs (here the example of the standard choral tenor  
clef)
% Semitone staves

\version "2.15.35"

\new Staff \with { \consists Ambitus_engraver } {
        \set Staff.middleCPosition = #1
        c' c''
}

\new Staff \with { \consists Ambitus_engraver } {
        \set staffLineLayoutFunction = #ly:pitch-semitones
        c' c''
}

--------------------------

I think the first example is expected behaviour but the second one is a new  
bug.
