/w, /msg, /tell all say: Usage: /tell <player> <privateMessage>

wether you type /w, /msg or /tell
the Usage is always: Usage: /tell <player> <privateMessage>
I expected it to be
/tell -> Usage: /tell <player> <privateMessage>
/w -> Usage: /w <player> <privateMessage>
/msg -> Usage: /msg <player> <privateMessage>

It is just a small bug... but bugs are bugs!
