I think that if we establish the rule "a broken beam decision is never
reconsidered" we can abolish the '* rule for beaming patterns and
instead let a non-specified minimal duration always be broken according
to the time intervals of its next-larger cousin.

That would simplify the default patterns, not cause problems when new
lengths get supported, and make it harder for users to specify patterns
manually with accidentally undefined behavior.
