(void) cb_set_tohit_mod(int mod)
/*
 * Function name: cb_set_tohit_mod
 * Description:   Apply a modifier to the base tohit value.  This
 *                differs from specifying a weight value in
 *                cb_update_tohit_val in that the mod will carry
 *                over to different opponents.
 * Arguments:     int mod - the modifier amount
 * Note:          The possibility of combat object cleanup should
 *                be taken into account when using this function.
