[O] fill text (indent) in lists

[Uwe Brauer]

Hello

Please consider the following example

  - Rzcrmnzbf pba Pnyphyb Ahzrevpb. FBYNZRAGR grarzbf qbf frznanf
    (FRVF UBENF RKNPGNZRAGR)
r vzcnegvzbf yb arprfnevb cnen unpre yn ubwn qr ceboyrznf:   reebe eryngvib l 
reebe nofbyhgb, ncebkvznpvba cbe
ry cbyvabzvb qr Gnlybe,
qrevinpvba r vagrtenpvba ahzéevpn, cbyvabzvb qr yntenatr, zrgbqb qr rhyre cnen 
RQBf.  

I would like to have a filling function which would result in the
following paragraph:

  - Rzcrmnzbf pba Pnyphyb Ahzrevpb. FBYNZRAGR grarzbf qbf frznanf (FRVF
    UBENF RKNPGNZRAGR) r vzcnegvzbf yb arprfnevb cnen unpre yn ubwn qr
    ceboyrznf: reebe eryngvib l reebe nofbyhgb, ncebkvznpvba cbe ry
    cbyvabzvb qr Gnlybe, qrevinpvba r vagrtenpvba ahzéevpn, cbyvabzvb qr
    yntenatr, zrgbqb qr rhyre cnen RQBf.


But that seems not possible with the current filling function, because I
obtain

    Rzcrmnzbf pba Pnyphyb Ahzrevpb. FBYNZRAGR grarzbf qbf frznanf
    (FRVF UBENF RKNPGNZRAGR)
    r vzcnegvzbf yb arprfnevb cnen unpre yn ubwn qr ceboyrznf:   reebe eryngvib 
l reebe nofbyhgb, ncebkvznpvba cbe
ry cbyvabzvb qr Gnlybe,
qrevinpvba r vagrtenpvba ahzéevpn, cbyvabzvb qr yntenatr, zrgbqb qr rhyre cnen 
RQBf.  

Most like this has to do with the indent-region function, but I would
like to know whether there is an easy solution to the problem presented.
