Use raw string when invalid escape sequence present. Those emit deprecation warnings at import/compile time so unfortunately we can't trap that with iptest as modules are already imported. The way to test that is to start IPython via `python -We -m IPython`, and we should try to likely do that in travis. But first fix all places that raise an error
