Then show me your reasoning.  I wish you are correct.

The current definition of File.split(path) is

  [File.dirname(path), File.basename(path)]

where POSIX dirname and basename are both defined to return "/" for
"/", the only reasonable return value is ["/", "/"], unless we change
the definition of File.split.
