I have
  \repeat volta 2 {...}
  \key b \hitzaz
  \acciaccatura as8 b4 ...
plus another staff with chord names below.

Then all kind of strange things happened: LilyPond added an extra end repeat 
sign with he key change and grace note before, sometimes the grace note before 
the key change. Adding \bar ":||" caused the repeat sign to disappear 
altogether.
