[Box Backup] Flaw in bbackupquery help

[Roy]

Hi all,

I just installed version 2520 on my Windows machine. When I started 
bbackupquery and issued a help command, I got the following:
query > help
Available commands are:
    bbackupquery
    list
    ls
    cd
    pwd
    lcd
    sh
    get
    compare
    restore
    getobject
    usage
    undelete
    delete
    quit
Type "help <command>" for more information on a command.

I think that bbackupquery itself is not an available command, so it must 
be removed from this list.

Another thing is that I don't really understand the use of undelete and 
delete. Both help text aren't totally clear to me. Can somebody explain it?

Cheers,

Roy
