Subject: [PATCH] Fixed a problem with evaluating indented lines in pure python code.

:meth:`EmbeddedSphinxShell.process_pure_python` could not process
block of code with indentation correctly. For example, the following

.. ipython:: python

   for i in range(10):
       if i < 5:
           continue
       else:
           pass

would result in two IPython lines:

In [19]: for i in range(10):
   ....:      if i < 5:
   ....:          continue
   ....:

In [20]: else:
   ....:          pass
   ....:

This would raise various types of error, indentation/snytax, etc.

To resolve this problem, added a simple check for indentation
in the next line which normally start a new IPython line.
