Ok, guess I misread the documentation.. I thought file used whatever
separator was appropriate for the platform, and that based on the note at
the end of "file join", "/" was for unix (forgot "/" was for win), and ":"
was used for Mac.

I guess that was my mistake in reading it - I suppose it means that / is
"root" for unix and win, and ":" is root for Mac, and "/" is used as path
separator everywhere?
