ltend: Reject zero amount more nicely

Browse source 
Unlike tend, ltend does nothing silently when asked to tend zero
commodities.  This may leave the player guessing why the command did
nothing.  Report the reason and fail the command, just like tend does.
While there, improve the prompt to match tend's.
