This looks like a bug at first glance, but it actually isn't one.  The
routine to break the line works backwards from the optimum wrap point,
and if the only blank it finds is the space you just typed at the
beginning of the a's, that's what it'll use.  Pico wraps its lines the
same way.

I'm guessing you're using the default fill of -8.  If so, the difference
in wrapping behavior is due to it.  When the stuff after the string of
a's is within 8 columns of the edge of the screen, it will be wrapped;
otherwise, it won't.
