I wasn't irritated by the default but by the behaviour when I change the 
default (-> giving me four short plus one long beam).
But that's obsolete now with the new version :-)

Well, at least *I* didn't get this syntax to clear the beaming rules 
from the documentation.

With the new code, LilyPond behaves as it should have done, i.e. if 
there are beaming rules the beatLength doesn't affect beaming.
But I don't see any change in the docs.
Can you tell me where I can find this new solution and how it works?
If it has been postponed it wouldn't be a real problem because now I 
have understood how the beaming works/worked

No, that's generally not what I intended, but it's interesting to know.
