Solution to have repeats with upbeat and different alternatives??

[steve]

Howdy!

         What is the solution to having repeats with upbeats and different
alternatives?
     As in Beethoven's opus 31 no4 the "Allegretto"

          This is the best that I can get with lilypond. There is a
extraneous bar in the last
second alternative of the last repeat???
