Code_prettify does not recognize IPython magic commands

[catch22]

E.g., using %%time raises the following error, which is probably straight from PyYapf:

[code_prettify]
Error: SyntaxError
invalid syntax (, line 1)

Not sure if you feel this is a code_prettify issue or a yapf issue.

This happens because yapf reformats python code and the IPython magics are not recognized. So this is really a syntax error.

It could be possible to preprocess the text from code cells to remove the magics (while leaving an anchor) and reinsert the magics after reformatting (but clearly this is not at my top todo). if somebody wants to give it a try, welcome!

I've looked at this before & recall concluding that the necessary preprocessing would have to be done by the relevant kernel. The ipython kernel does this line-by-line, but I couldn't find a simple way to separate the preprocessing from the execution, iirc.

@jfbercher Thank you very much!
