The code.InteractiveConsole() is useful to emulate a python console.  However, any code currently "push"ed to it must be single statements.  This is because it passes the ´single´ symbol mode to the underlying compile function.
This patch allows the caller of InteractiveConsole.push to specify a different mode, e.g. ´exec´.  This is useful if one wants to paste entire code snippets into the console.  Without it, pasting the following:
'if True:\n  print 1\nprint 2' Won't run.  pushing such multiline code snippets with an additional 'exec' argument will allow it to work.
Patch included.

Note, there are no regression tests for the code module.

Here is how to test this manually:
from code import InteractiveConsole
c = InteractiveConsole()
s = "if True:\n  print 1\nprint 2"
c.push(s)  #fails
c.push(s, "exec")  #succeeds

Please can you starts a small test suite for the code module that tests the fix you are proposing and include it as another patch?
