Slashes in file names

Yup - in fact, that dates all the way back to V7, and even earlier (I
don't think V6 disallowed them, either - dunno if any of its
predecessors did).

It is different.  4.1BSD disallowed the character '/'|0200, and 4.2BSD
and successors disallowed any characters with the 8th bit set.
