Hrmpf, just an hour after sending that mail, I found the correct solution 
while reading the parser.yy: If you append \! to the figure, its extender 
will be broken, so the correct way to get something like:
    6 ______   6 ______
    4  4  4  4   4  4  4  4
is simply:
    \set useBassFigureExtenders = ##t
    <6 4>8 <6 4\!> <6 4\!> <6 4\!>   <6\! 4\!>  <6 4\!> <6 4\!> <6 4\!>

Unfortunately, that's not documented (I've now added a snippet to the LSR)... 

What I'm missing anyway is a complete syntax overview for figured bass and for 
chords. Something like:
~~~~~~~~~~~~~~
A figured bass entry [TODO: enter correct term...] is of the form 
   < //number//modifier(s) ...  >duration
where number is either a number or _ to indicate an empty number, which still 
takes space and displays any modifiers attached to it.
Supported modifiers (multiple modifiers per number are possible):
       + ... Raises the corresponding step (a sharp is shown)
       - ... Lowers the corresponding step (a flat is shown)
       ! ... Forces a natural step (a cancel sign is shown)
       \+ ... Augmented step (a plus is shown)
       / ... Diminished step (a forward slash through the number)
       \! ... Forces a breaks of any extender assigned to that step
There is no modifier for placing a backward slash through the number 
(typically used indicating a raised sixth step).
One or more of the figures can also be placed between square brackets, e.g. 
[ //number//modifier(s) //number//modifier(s)], to print square brackets 
around these numbers.
Instead of //number//modifier(s), one can also enter a full markup.
~~~~~~~~~~~~~~


Similarly, I'm missing a table of all possible chords (maj, min, dim, etc.) in 
chord mode.

Cheers,
Reinhold
