SYNOPSIS
        int remove_input_to (object player)
        int remove_input_to (object player, string fun)
        int remove_input_to (object player, closure fun)
        int remove_input_to (object player, object fun)
        int remove_input_to (object player, object ob, string fun)
DESCRIPTION
        Remove a pending input_to from the interactive <player> object.
        If the optional <fun> is not given, the most recently added input_to
        is removed.
        If the optional <fun> is given, the efun tries to find and remove the
        most recently added input_to matching the <fun> argument:
         - <fun> is a string: the input_to functionname has to match
         - <fun> is an object: the object the input_to function is bound to has
                               to match
         - <fun> is a closure: the input_to closure has to match.
         - <ob> and <fun> are given: both the object and the functionname have
                               to match
        Return 1 on success, or 0 on failure (no input_to found, object is not
        interactive or has no input_to pending).
EXAMPLES
        // Remove all pending input_to from the current user, if any.
