Add set_repeat_arguments function

Browse source 
The "x", "list", and "show commands" commands have special repetition
behavior: repeating the command doesn't re-run it with the same
arguments

This is currently implemented by modifying the passed-in argument; but
that won't work properly with const arguments (and seems pretty
obscure besides).

This patch adds a new "set_repeat_arguments" function and changes the
relevant places to call it.
