Help with use of code.InteractiveInterpreter for multiline code

[Jean Brouwers]

Take a look at the source code of the code module (file code.py in the
lib directory).  The push() method of the InteractiveConsole class
shows how to handle multi-line statements.

Basically, keep collecting lines as long as the result returned by the
runsource() call is true.  Maybe instead of calling the runsource()
method, just call the push() method.
