Misleading autobeaming in 3/4

[Bertrand Bordage]

Hi everyone!

(I don't know if we can call this a defect, so I don't send it to bug-lilypond for the moment)

I am working on a 3/4 score with this rhythmical pattern in the beginning : "4. 8 8 8".

It is repeated five times, but the rest of the score is clearly in 3/4 and not 6/8, contrary to what this pattern suggests.

It is therefore important to have a beaming that suggests 3/4, even if it's already written at the beginning.

But here's what happens:

%%%

\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. }

%%%

Is there any way to fix this globally instead of having to add \noBeam everywhere?

Thanks,

Bertrand
