This section in the manpage is preceded by
      By default, under MS-DOS  and  MS-Windows,  grep  guesses whether  
a  file  is  text or binary as described for the --binary-files option.
which may be interpreted so that this stripping only occurs in the 
DOS/Windows versions, which the cygwin version isn't.
If you think this is unclear, as the Linux version behaves the same way, 
you should report this upstream.
