Figured Bass Accidentals are misaligned. I need them shifted up.

[Nils]

Hello,

When using accidentals stand-alone in figured bass <_+ _! _-> you'll notice 
that they are shifted down. I need them shifted up. How do I do that (in 
general, not one by one).

Related: I already applied this patch which makes accidentals the same size as 
normal figures. I wonder why this is not in the release since the patch is 2 
years old.

So I would be happy to rewrite that part to shift the accidentals up to the 
correct position. I just don't know how :)
