Actually, I think you can setup through the mostly undocumented style_t enumeration for using a "/" but it is not automatic as I recall. See cmdline.hpp for the style_t definition. It also took a little looking to figure out how to set style_t. I did it once a couple of years ago and I forget offhand how I did it but could find it if needed.
