It's discussed in some of the linked references in the Slashdot
discussion.  One suggestion was that / was used as a prefix for
command modifiers (/X /A etc.) so it would be slightly harder
to parse.  Certainly command arguments preceded folders, both
in CP/M and QDOS.

Not many people know this, but at low levels in old Mac OS,
they used ":" as a folder separator in file specifiers.
