Oops.  I should elaborate a little more about this.

The first beaming pattern used to be the default in certain cases
(e.g. 4/4 time on beats 1 and 3), and this beaming pattern can still
be used by modifying beatLength, as Trevor described.

But it is reasonable to expect users to use "\set beatLength =
#(ly:make-moment 1 2)" if they want the first beaming pattern, which
is more common?
