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));
It should read :
i = comp->cmd_function(mtfd, comp, argc - argn,
Fixed in mt-st-0.5b AFAICT
