nbconvert: backslashes are not escaped when converting to LaTeX

[rossant]

If a cell contains a backslash, say, the following line in output:

Opening "C:\path\myfile"...

then the conversion to LaTeX fails: "\path is an undefined control sequence". This especially happens on Windows!

This doesn't seem to be a problem anymore (tested on master).

I used

print 'Opening "\\home\\path\\nb.ipynb"...'

to print the output which was then converted using

$ ipython nbconvert i3588 --to latex --post pdf
