nbconvert on windows: tex and paths

[rhewett]

When nbconvert is used to produce latex files (either through format=latex or format=sphinx_*) on Windows, the paths that are put into the file are of the form:

\documentclass[letterpaper,10pt,english]{C:\Anaconda\lib\site-packages\sphinx\texinputs/sphinxhowto}

The problem is those backslashes are treated as latex commands, which produces errors.

Latex accepts forward slashes on windows just fine. I'm not sure if there is a way to force python's os.path tools to produce the right thing for this case, and I can't find in the code where these things are set, so I have not been able to muck about with it.
