SYNOPSIS
        void ed()
        void ed(string file)
        void ed(string file, string func)

DESCRIPTION
        Calling without arguments will start the editor ed with the
        name of the error file, that was returned by
        master->valid_read(0, geteuid(this_player()), "ed_start",
        this_player()), usually something like ~/.err. If that file is
        empty, ed will immediatly exit again.
        Calling ed() with argument file will start the editor on the
        file. If the optional argument func is given, this function
        will be called after exiting the editor.

        The editor ed is almost ed(1) compatible.
