Hi Ralph,

The LSR snippet you mentioned still works just fine in 2.19.81.  If you 
would post an example of how you have tried to use it, we may be better 
able to help you track down what isn't working for you.

Now, since setting repeat commands can be a little tedious, I have been 
using the following helper functions since 2.10.33, with minor 
alterations over the years:

%%%%
  \version "2.19.81"

  startRepeat = \set Score.repeatCommands = #'(start-repeat)
  startVolta = #(define-music-function (text) (markup?)
    #{ \set Score.repeatCommands = #(list (list 'volta text)) #})
  changeVolta = #(define-music-function (text) (markup?)
    #{ \set Score.repeatCommands = #(list '(volta #f) 'end-repeat (list 
'volta text)) #})
  endVolta = \set Score.repeatCommands = #'((volta #f))
  endVoltaStartRepeat = \set Score.repeatCommands = #'((volta #f) 
start-repeat)
  endRepeat = \set Score.repeatCommands = #'(end-repeat)

  \relative c'' {
    \startRepeat
      f4 g a b |
    \startVolta \markup \text \small "1, 2, 3, etc."
      g4 a g a |
      c1 |
    \changeVolta \markup \text \small "Last time"
      b4 a g f |
    \endVolta
      e1 \bar "|." |
  }
%%%%

NOTE: I included \endVoltaStartRepeat and \endRepeat, but they were 
unneeded for the example.
