Long StanzaNumber collides with the left vertical line connecting staves

[Sietse Brouwer]

Dear all,

StanzaNumber precedes the lyrics, and extends to the left. If it becomes wide 
enough, it crosses the vertical line which connects the staves of a system 
(assuming a multi-staff system). 

Proper behaviour would probably be to shift the start of the notes and lyrics 
to the right, and space the starting matter (clef, timesig, keysig) accordingly.

Preceding a normal one-digit number with a mezzoforte dynamic is wide enough to 
cause a collision. The example below has a five-digit stanza number, which is a 
bit rare in practice, but otherwise equivalent and simpler.

Example code:

\version "2.10.11"

\layout { ragged-right = ##t }

verseOne = \lyricmode {
        \set stanza = "44444. "
        Ma -- ry Su -- san
}

\score {
        \new ChoirStaff <<
                \new Staff = upper {
                        \new Voice = "voiceOne"
                        a'4 b'4 c'4 d'4
                }
                \new Lyrics \lyricsto voiceOne \verseOne
                \new Staff = lower {
                }
        >>
}
