And classic Macintosh OS has much the opposite convention.  its
directory level separator is ':'.  And "FOO:BAR" is taken as fully
qualified; ":FOO:BAR"  is relative to current directory.  But a
single qualifier, no colons, "FOOBAR" is always current directory
relative.  There's some Bad History there.
