Will do.

Haven't done yet.

if that's
OK.  It'd require a lot of deleting and moving around, and I'd first
like to
make sure that these stubs are the code base and bug free for a while
before I
deprecate an entire grob (and figure out how to deal with the syntax
that come with said deprecation).

Well, the SpanBarStub extent is not the full length to bridge between
BarLines, it is only the height of the Lyrics, and only those Lyrics in
the neighboring measures.

SpanBarStub needs to change size, or get a bar-extent different from its
Y-extent, before it can take over the job of printing SpanBars.

I'm worried the code will be quite difficult to understand for quite a
while unless Mike retreats.
