Figured bass spacing problem

[Mark Hymers]

Hi,

I'm trying to typeset some figures bass:

Here's an example:

bassH = \figures
{
\skipHBass
r2.
<_+>4 <_+> <_+>
r2.
r2.
r2.
r2 <6>4
r2.
<_+>4 <_+> <_+>
r2.
<_+>4 <_+> <_+>
r2.
r2.
r2 <6>4
<_-> <_-> <_- 6>
<_+>4 <_+> <_+>
r2.
}

\skipHBass simply skips to the relevant part of the score.

The problem is that when I'm trying to display an accidental without a
number it doesn't line up properly.

So, for example (#=sharp, b=flat !=natural):

4#
 b

instead of
4#
b

This is a big problem when only displaying a # sign as it doesn't line
up with the note above it.  I notice from
http://www.lilypond.org/stable/Documentation/user/out-www/lilypond/Figured-bass.html#Figured%20bass
that it seems to work (the natural sign in the <_! 3+ 5-> lines up
perfectly there.  I'm using 1.7.17 - is the behaviour known to be broken
in this release?

Thanks,

Mark
