Re: time signature: 3.5/4

Hi Stefan,

Well...  =\

My OCD won't let you use that version — at least this one fits in the  
staff, like a good time signature should:

\version "2.13.7"

tsa = \markup {
  \override #'(baseline-skip . 0)
  \center-column {
    \concat {
      \number 3
      \raise #0.5 "+"
      \raise #0.75 \fontsize #-4 \number "1"
      \translate #'(-0.1 . 0.2) \fontsize #0 "/"
      \translate #'(-0.1 . 0) \fontsize #-4 \number "2"
    }
    \number 4
  }
}

music = {
  \once \override Staff.TimeSignature #'X-offset = #1.75
  \once \override Staff.TimeSignature #'style = #'default
  \once \override Staff.TimeSignature #'stencil = #(lambda (grob)
    (grob-interpret-markup grob tsa))
  \time 7/8 R8*7
}

\score { \music }

Really, the "+" and "4" should be centred, I think, with the "3" and  
"1/2" sitting on either side... but I've got other work to do.  =)

Cheers,
Kieren.
