  # the untainting pattern for Windows used by File::Find seems to be wrong.
  #
  #  - cwd returns an absolute directory will usually return a volume (e.g. 'C:')
  #  - windows file systems frequently include directorieswith parans and spaces in them
  #    I am a little dubious that accepting them is safe.  The alternative is that
  #    this module would not be installable in a lot of environments, and I honestly
  #    don't believe that many people are using Test::Version in taint mode on Windows
  #    anyway, so I am weighing the risk as worth it.
  #  - windows has short names with tildes in them (e.g. "FOO~1").  Tilde is not a
  #    special character in windows shells anyway, so I think we should be safe there.
