[PATCH] pk-repl: inform the inputrc parser of the program name

[Arsen Arsenović]

This allows users to conditionally adjust their readline preferences
based on whether they're using Poke.

        * poke/pk-repl.c: Set rl_readline_name to "Poke", to inform the
        inputrc parser about who we are.

Afternoon,

This patch should permit the use of the $if construct in .inputrc to create
Poke-specific readline adjustments, for example:

        set editing-mode vi
        set show-mode-in-prompt on

        $if Poke
        set editing-mode emacs
        set show-mode-in-prompt off
        $endif

Thanks.
