Fix for port-Makefiles

[R.Brouwer]

Dear ,

I regularly receive the error "warning: String comparison operator 
should be either == or !=" when I rebuild the ports-index.
Or the error: Malformed conditional ((${OSVERSION} < 503001 && 
${OSVERSION} >= 500000) || (${OSVERSION} < 492000))

To prevent these errors I correct all errounious information in port 
Makefiles with the following script:
======== fix_makefiles.sh ====
#!/usr/local/bin/bash
FILES=`find /usr/ports/ -name Makefile* -exec egrep -l " [0-9]+[)]"  {} \;`
for i in ${FILES}
do
    # Process all files with an number and connected )
    mv $i $i.old
    # Add a space after the number
    if [ -f $i.old ] ; then
        sed -E "s/( [0-9]+)[)]/\\1 )/g" <$i.old >$i
    fi
done
==========================

This script is placed in the daily cron line as follows:
/usr/local/bin/cvsup -g -L 2 /usr/local/etc/ports-supfile -l 
/var/run/ports-update.lock >/var/log/ports-update.log ; 
/usr/local/bin/fix_makefiles.sh; /usr/local/sbin/portsdb -Uu

I don't know if it is useful to have this functionallity somewhere in 
the freebsd software. For me this works just fine.

Kind regards,
