There is a problem with mt-st-0.5.  For the 'mt' commands
processed by the 'do_standard' function, the count arguments
are not processed properly and are always treated as 0.

The problem is in 'mt.c' line 285 while reads :
  i = comp->cmd_function(mtfd, comp, argc - 2, &(argv[2]));

It should read :
    i = comp->cmd_function(mtfd, comp, argc - argn,
&(argv[argn]));
