File cell magic fails with blank lines

[markusbaden]

When trying to write a notebook cell to a file via the %%file magic only the content above the first blank line is written to the file. The rest is executed as normal python code. For more details see a gist with an example on nbviewer

Thanks - we're already tracking this as issue #3178, and I'm working on code to fix it.

Ok. Thanks, and sorry for the duplicated issue.
