This is not a bug.  There is still a general auto-beam
setting for 3/4 time which inhibits beatGrouping.

beatBrouping should work with the override

#(revert-auto-beam-setting '(end * * 3 4) 3 4)


I was waiting for 2.13 before I completed this work, as
changing the default beaming did not seem right during
a stable release.
