Don't some church modes have an optional flat?

Of course, you're right about the black-key scales, which
is the pentatonic scale I've used.  But they can still be
defined with different note names.  Which would we choose?

I think the revision is pretty well complete now.  If
there are no further comments I'll push this on Saturday.
All the comments have been on the documentation anyway.
Mike's code looks good.

Whatever we decide about defining some scales I'd want
to make that a separate patch anyway, so we don't have
to wait for this discussion to crystallise.
