File => Save as '.py' saves magic as code

[arokem]

Saving a notebook as a .py file, I noticed that the cell:

%pylab inline

Was exported as is to the '.py file (not commented). Should lines with magics be commented on export?

yup - it's wrong. There are two things to do here:

1. save as .ipy, an IPython script (what we actually do)
2. save the transformed pure-Python input as .py (what we say we do)

I currently dont see the File --> Save as option in the notebook menu.
