It is possible for the log to be filled too quickly for the consoles
to be able to keep up. This is detected in console_unlock(), and when
it occurs, a message is inserted to note the event. When reviewing
some nearby code, Petr Mládek suggested it might be nicer if this
message were placed on a separate line. This patch implements that
suggestion.
