Question about adding a new option vs extending an existing one

Hello,

I'm interested in writing a patch for GDB which allows a user to change the=
 radix used for displaying function offsets in instruction listings (exampl=
e below), right now it only uses decimal, and doesn't respect the existing =
radix settings (either `radix` or `output-radix`).

I want to contribute a patch that allows the user to change the radix used =
for displaying these offsets, but I'm not sure if it would be best to re-us=
e the value of `output-radix`, or to define a new setting (eg, `offset-radi=
x` maybe).

Additionally, if a new option should be added, would it be appropriate to h=
ave `set radix` also set that new one (I would assume yes).

Does anyone have any opinions on this? My personal feeling is that reusing =
`output-radix` would be best.

(gdb) set radix 16
Input and output radices now set to decimal 16, hex 10, octal 20.
