 We could reword output from `set architecture' so as not to suggest the 
use without an argument is invalid.

 In any case the listing facility must not be an `info' subcommand, as 
these are meant for showing the state of the debuggee, while the set of 
architectures supported is a property of the given instance of GDB itself, 
and therefore suitable for the `set'/`show' commands.  So if a new command 
it would have to be `show architecture list' or suchlike.

 BTW is there a way to globally disable styling by default?  I find it 
irritating (it distracts me and hurts my eyes) as I do having to type:

(gdb) set style enabled off

every time.  Placing the command in $HOME/.config/gdb/gdbinit or 
$HOME/.gdbinit does nothing, the welcome message is still a disturbing 
mixture of colours.
