cowsay --help gives output that hints at incompatible perl usage

[Daniel Kessel]

Running 'cowsay --help' on vivid gives this, which looks like it is broken:

usr/games/cowsay version [unknown] calling Getopt::Std::getopts (version 1.10 [paranoid]),
running under Perl version 5.20.1.

Usage: cowsay [-OPTIONS [-MORE_OPTIONS]] [--] [PROGRAM_ARG1 ...]

The following single-character options are accepted:
        With arguments: -e -f -T -W
        Boolean (without arguments): -b -d -g -h -l -L -n -N -p -s -t -w -y

Options may be merged together. -- stops processing of options.
Space is not required between options and their arguments.
  [Now continuing due to backward compatibility and excessive paranoia.
   See 'perldoc Getopt::Std' about $Getopt::Std::STANDARD_HELP_VERSION.]
