Good work Johannes.

Actually Pascal allows any lower-bound. nspace[0] is
okay but stave_size[0] is not. But the bug is that the
begin...end block is *not* the body of the third loop and i
isn't even defined there.

I'm guessing that the begin...end block is spurious and
should simply be deleted. Dirk?
