   Does anyone know why the "tty" command gives the "default" message when
   I have,

      /* add the filename of the terminal connected to inferior I/O */
      add_setshow_filename_cmd ("inferior-tty", class_run,
				&inferior_io_terminal, _("\
      Set terminal for future runs of program being debugged."), _("\
      Show terminal for future runs of program being debugged."), _("\
      Usage: set inferior-tty /dev/pts/1"), NULL, NULL, &setlist, &showlist);

      add_com_alias ("tty", "set inferior-tty", class_alias, 0);

   I would expect the alias to take on the usage note from the command it
   points to. Either that, or allow me to explicitly give it a usage note.
   Any suggestions?

But it does take the usage nore from the command it points to:

(gdb) set inferior-tty
Argument required (filename to set it to.).
