Simon, 

A few weeks ago, I added a new time signature style named "single-C” which can 
be used with \time 2/1 to give you a cut-C symbol with a measure length of one 
breve.  The reception from a couple other people involved in our discussions 
was not very enthusiastic, but I never heard from you.

I have just posted a patch for review[1] which allows the alternative solution 
of defining your own time signature style:

#(add-simple-time-signature-style ’simons-alla-breve
   (lambda (fraction)
     (let ((n (car fraction))
           (d (cdr fraction)))
    (if (and (= n 4) (= d 2))
        (make-musicglyph-markup “timesig.C22”)
        (make-c-time-signature-markup fraction)))))

If the patch is accepted, including this code in your lilypond file would allow 
you to use the style “simons-alla-breve” to get the cut-C symbol with \time 
4/2, with other time signatures appearing identical to the “C” style.

Please let me know which of these solutions appeals more to you.  If you prefer 
defining your own style rather than using single-C, then I think single-C 
should be removed rather than documented.
