Repeat alternative count

[Dan Eble]

Is there a use case for specifying the number of times to reuse a repeat 
alternative in a way that \unfoldRepeats could honor?  Right now, it reuses the 
first alternative enough times to reach the repeat count.  If so, does anyone 
want to suggest a syntax?  Here's my entry.

    \repeat volta 40 {
      …
    } \alternative {
      { … }
      \repeat alternative 3 { … }
      { … }
    }

Good? Bad? Meh?
