Misleading autobeaming in 3/4

[Bertrand Bordage]

Hi again,

There's a small defect in autobeaming:

%%%
\markup "This:"
\relative c'' { \time 3/4 a4. b8 c d e d c b4. a8 b c d c b a2. }
\markup "looks like 6/8:"
\relative c'' { \time 6/8 a4. b8 c d e d c b4. a8 b c d c b a2. }
\markup "but should be like this:"
\relative c'' { \time 3/4 a4. b8\noBeam c d e d c\noBeam b4. a8 b c d c b
a2. }
%%%

Unfortunately, I don't think this can be easily fixed with the current
system.

Regards,
Bertrand
