   The bpo-13183 raises the problem that when the trace function is not
   set in the caller frame, the step command fails at a return statement.

   This new issue raises the point that, for the same reason:

   * the next, until and return statements fail also at a return
     statement when the caller frame does not have a trace function
   
   * when the user runs the up and down commands at any line in a
     frame to select a new frame, then the next, until or return
     commands fail when the selected frame does not have a trace
     function
   

   The attached patch fixes all those problems (by first removing the
   changes made in bdb.py at bpo-13183).

   After the patch, the implementation ensures now that self.stopframe is
   either None, or belongs to the stack frame in the interval
   [self.botframe, self._curframe] and that it is set to self.botframe
   when the debugging session terminates. This allows removing the while
   loop in stop_here with an improvement in the performance of Pdb (since
   stop_here may be called at each line, even when no breakpoint is set
   in the function).

   The patch applies to the default branch and includes 5 new test cases.
   A patch for 2.7 will be submitted later.

   Since this pdb issue is a continuation of bpo-13183 and repeals a part of that issue's patch, I nosy'ed the contributors to that issue.
