accidental too far away from notehead

[Werner LEMBERG]

Please consider this code:

  \version "2.17.10"

  \relative c''' {
    << { <gis cis eis gis>2 } \\
       { eis,2              } >>
  }

Attached you can find an image.  I think this is a formatting bug of
lilypond: The e sharp in the second voice should be directly placed in
front of the notehead since it is not part of the chord.  However, I'm
not sure, thus I'm writing to this mailing list :-)

Is there a possibility to make lilypond automatically move the
accidental in the lower voice to the right so that it is not aligned
with the accidentals of the upper voice?
