Bogofilter contrib scripts treated as docs

[RW]

I just noticed that the bogofilter perl and shell scripts from the contrib
directory (see below) only get installed if bogofilter is built with the 
DOCS option.


.for i in bfproxy.pl bogofilter-milter.pl bogo.R bogofilter-qfe.sh \
       mime.get.rfc822.pl parmtest.sh printmaildir.pl \
       bogominitrain.pl \
       randomtrain.sh scramble.sh spamitarium.pl stripsearch.pl trainbogo.sh 
     ${INSTALL_SCRIPT} ${WRKSRC}/contrib/${i}  ${STAGEDIR}${DOCSDIR}/contrib/${i} 
.endfor
