Repeat bars don't connect

[Marcel Bollmann]

Hi! 
 
In a piano piece which I am typesetting, there is a repeat bar which 
starts at the beginning of a line. LilyPond, however, doesn't connect the 
repeat bars of the two piano staves in this case (in all other cases, it 
works just fine). I'm using LilyPond 2.2.0. 
 
Here is a short example which produces the described output: 
 
% --SNIP-- 
\version "2.2.0" 
\score{ 
\context PianoStaff << 
  \new Staff \notes {c'2 c'|c' c'| \break 
     \repeat volta 2 {e' e'|e' e'} } 
  \new Staff \notes {\clef bass c2 c | c c | e e | e e} 
>> 
\paper { } 
} 
% --SNIP-- 
 
Trying to add the connection manually using 
  \override Score.SpanBar #'glyph = #'".|" 
places the desired connection at the end of the previous line. 
 
Am I doing something wrong? Could this be a bug? Or are repeat bars just 
not supposed to be at the beginning of a line? (Like I said, the sheet 
music I'm typesetting has them exactly there.) 
 
Thanks, 
- Marcel
