OK, so this isn't some new feature I hadn't heard about due to my
spending most of my time with 2.7. :)

Yep, I knew that -- I have always use forward slashes on Windows (and
DOS before that) when dealing with the file system.

Yup, I was wondering if that was where Python (or its stdlib) would
convert them (which would have surprised me).  Back in the day, you
could change the 'option switch' character from '/' to whatever you
wanted (and as an old Unix guy, I always set it to '-').  Then you
could even use forward slashes on the command line (mostly). But, I
don't think Windows has support that for yonks.
