This confused me a lot while changing something in Sphinx.
Also maybe someone who knows what he's doing should probably have a look if it really should be \\ (which is a newline in LaTeX if I have read correctly) and not better a \backslash. In both cases of course for the docs and the latex output. I am not good enough at LaTeX macroing to really know for sure. This change simply synchronizes the docs with what is actually happening in the Parser, no matter if it's right or wrong.
