Update documentation for Python Frame.older and Frame.newer

Browse Source 
I noticed that Frame.older and Frame.newer don't document that they
return None at the ends of the stack.  This patch updates the
documentation, and also fixes a somewhat related typo in a comment
that I noticed while digging into this.
