arogue7, xrogue: fix command repetition.
In both games, command() loops and calls the action function twice for
each command: once to schedule it by setting player.t_action and
player.t_no_move, and again, to actually do it, once player.t_no_move
has been reduced to 0. Each loop decremented count, so repeated
commands were only repeated half the number of times the player typed.
count is now decremented only when ch has been set to the repeated
command.
