Bad image with one of the snippets

[Patrick Horgan]

In snippet no. 433 the Rehearsal Marks don't have the alignment you 
might expect.  Grabbing down the snippet and compiling it with the 
current lilypond works fine and produces the desired result, but in the 
image in the snippet, the alignment of the
rehearsal marks never move.  It made it quite confusing when I looked at 
it.  Could someone generate a correct image for it?
