Didn't know that. More importantly, I had thought forward slashes were
valid file basename characters, but Windows is surprisingly strict about
that:

   < > : " / \ | ? * NUL

are not allowed in basenames. Unix/linux disallows only:

  / NUL

In fact, proper dealing with punctuation in pathnames is one of the main
reasons to migrate to Python from bash. Even if it is often possible to
write bash scripts that handle arbitrary pathnames correctly, few script
writers are pedantic enough to do it properly. For example, newlines in
filenames are bound to confuse 99.9% of bash scripts.
