Bug in stem/accidental collision

[Sebastiano Vigna]

Dear developers,
the following example (from Scarlatti K460) shows a collision between a
stem and an accidental (third measure):

\score {
           \context Staff = upper {
           \time 2/2
           \key c \major
           \relative c'' {
              { c4 g'8 c, b4 c }
              <<
                { g'4 f8 es d4 c 
                bes2 des' ~ des4 c8 bes aes4 g } \\
                { aes,2 \tieUp aes' ~ aes4 \tieNeutral bes8 aes g4 f e2 r }
              >>
           }
          }
}


I was easily able to fix it using forced hshift and right padding on the
accidental.
