    Don't fast forward past the end of a message.
    
    This is nice change for users of the voicemail application.  If someone gets a
    little carried away with fast forwarding through a message, they can easily
    get to the end and accidentally exit the voicemail application by hitting the
    fast forward key during the following prompt.
    
    This adds some safety by not allowing a fast forward past the end of a message.
