loadkeys command is not working correctly

Hello,

I try to set up a KeyboardInterpreter but without success.

the parameters to load the interpreter are:

loadkeys [country] [region]

when i try : JNode /> loadkeys ES
or i try: JNode /> loadkeys FR fr
the response of the shell is : "No matching syntax found".

but if i try: JNode /> loadkeys country region
the response of the shell is: "ERROR [KeyboardInterpreterFactory ]: KeyboardInterpreter for COUNTRY_REGION not found"

and then an exception:
Exception in command:
java.lang.IllegalArgumentException(): KeyboardInterpreter == null
.......

It seems that the command parser is confusing the arguments in the syntax matching.

Thank you.
