Chord tremolo bugs

[Mats Bengtsson]

Hi,

This example illustrates two bugs in the chord tremolo
implementation. At least the flags misplacement is a new
bug since 1.5.52.

\score{\notes\relative c'{
  c1:32 | % Flags too far to the left
  \repeat tremolo 16 {c32 e} g4 | % Flags too far to the left
  \repeat tremolo 12 {c32 e} g4 | % Wrong note head, missing dot on c,e
}}

Also, how difficult would it be to get the note spacing correct
also for chord tremolos?
