OS X does in the GUI; they're isomorphic to ‘:’ at the UNIX level. (The Mac used ‘:’ as the directory separator.)

  And a : in a file name at the GUI level gets turned into a dash! I just tried to name a text file "Foo/Bar 10:01.rtf" and it changed it to "Foo/Bar 10-01.rtf"!

    In that case the GUI is merely changing the file name you type; in a shell you'll see it as "Foo:Bar 10-01.rtf".
