Never print --more-- on its own line. Fixes #26

I've removed the code that causes --more-- to waste a line when the status window is taller than one line. 

In regards to Russ' comment that occasionally --more-- appears when there is still room in the window: as far as I can see, this only happens when pause_messages() is called because something noteworthy (like dying) is happening.  I don't see a reason to change this behavior necessarily, though the '--more--' message could be changed to something more appropriate in such a situation.
