Cleaning up auto-beaming

[Carl D. Sorensen]

Trevor,

In your commit b3f08b20010f377fb56de90053c2a245dc99d4d5 you cleaned up
the beam settings in autobeam.scm.

I think there are couple in there that could still be eliminated, by setting
beatGrouping in ly/music-init.ly (in the alist constant for
standard-beat-grouping).

+    ;; in 3 4 time:
+    ;;   override beatLength which would end beams at 1 4 beats
+    ;;   end beams with 16th notes each 1 4 beat
+    ;;   end beams with 32nd notes each 1 8 beat
 
+    ((end * * 3 4) . ,(ly:make-moment 3 4))

I think this one could be eliminated by means of an entry

((3 . 4) . (3))


+    ;;   override beatLength which would end beams at 1 4 beats
+    ;;   end all beams at 1 2 beat
+    ;;   end beams with 8th triplets each 1 4 beat
+    ;;   end beams with 16th notes each 1 4 beat
+    ;;   end beams with 32nd notes each 1 8 beat
 
     ((end * * 4 4) . ,(ly:make-moment 1 2))


And this one could be eliminated by means of an entry

((4 . 4) . (2 2))


IMO, this would be preferable, because it's easier to change, but
I'll accept your decision, since you're the one who's been working
this whole issue.

Thanks,

Carl
