Well, it's not only groff which complains.  Using heirloom troff,
which is *much* nearer to the original AT&T implementation, you get
the same warning:

  troff -x3 ...

    troff: .el without matching .ie; line 4
    troff: .el without matching .ie; line 5

You have to live with that limitation. :-)
