Steps to reproduce
Type /help then a number greater than 4
Observe your chat box
It will say 'unknown command' even though it should say 'the number you entered is too big'

Maybe /help is implemented not as a single command with a numerical parameter, but as multiple commands, with the number as part of the command.
It seems (to me) like it would be a bit more efficient to program it this way.
Confirmed.
