A question about Cmd Class

[yuan zheng]

Thanks.

I understand your code , and print it.

*Before replace:*
`~!@#$%^&*()-=+[{]}\|;:'",<>/?
*
After replace:*
`~!@#$%^&*()=+[{]}\|;:'",<>/?


Certainly, the charactor ‘-’ has been deleted from delims.
But there is nothing effect on my program after adding the code.

My shell：
---------------------------------------------------------------------------------------------------------------------
<Mycmd> l<TAB>
list-bp        list-machines  list-modules   list-options   load-conf
log-bus        ls
<Mycmd> list-<TAB>
........ NOTHING...
---------------------------------------------------------------------------------------------------------------------

The mean is that when I input "l", and then hit "TAB", it can list all optional
cmd.
But when I input "list-", and then hit "TAB", there is nothing.




thanks,
yuanzheng.
