For the past 8 years or so there never been confusion whether -f
was a pipe(8) option. I added a workaround for GNU getopt damage

Likely he is using a GNU INCLUDE file and it screws up

This has never been a problem on FreeBSD up to 6.0 which is
running Postfix just fine.

I just verified again that Postfix sendmail handles -- correctly.
