need to trim space at end of python code for doctest.

[GoogleCodeExporter]

Doctests are extremely unforgiving. Suppose a user has to write code
to satisfy the following doctest written by a tutorial writer
>>> double(1)
2 

where, there's extra blank space i.e., rewriting the code using "_" to
indicate white spaces, we'd have
>>>_double(1)
2____

... it would be essentially impossible for the end user to realise what is
wrong.  To prevent something like this from occurring, lines of code should
be trimmed from any extra spaces.

Fixed prior to release 1.0alpha1 but forgot to note the change here.
