4.2.1.6 Fuzzy Match Support

DCS-3950 series switch shell support fuzzy match in searching command and
keyword. Shell will recognize commands or keywords correctly if the entered string
causes no conflict.
For example:
1. For command 'show interfaces status ethernet 1', typing 'sh in e 1' will work
2. However, for command 'show running-config', the system will report a '> Ambiguous
command.
3. A '?' immediately following a string. This will display all the commands
that begin with that string.
