Please record the following as an enhancement request.

A quite commonly used notation for augmented steps is to draw a line  
through the
eventually elongated last line of the digit. In this case "Last line"  
refers to
the order the digit is written manually. This results in a typographic  
ligature
of the digit together with a plus sign.

In case of the augmented sixth the result should be like the following  
example
http://de.wikipedia.org/w/index.php?title=Datei:Altsext.gif&filetimestamp=20090401171647
This is better readable then the result of the following snippet

\version "2.12.3"
\figures {
 < 6\\ >4
}

Similar should be possible together with the figures 2,4,5. Here the  
resulting
plus sign isn't rotated but its is lowered or highered with respect to the
result of

\version "2.12.3"
\figures {
 \set figuredBassPlusDirection = #RIGHT
 < 5\+ 4\+ 2\+ >4
}

A poor graphical representation is given in
http://www.robertkelleyphd.com/FiguredBass.pdf where the vertical position  
is
o.k., but it's not really a ligature.

It is quite obvious that the result may be depending on the font used for  
the
digits.

A possible notation might be to use the \+ modifier and switch between the
current and the intended behaviour with a property (e.g.
 \set figuredBassPlusLigature = #TRUE)
