CFT: BSD-licensed grep [Fwd: cvs commit: ports/textproc/bsdgrep Makefile distinfo]

I use the following construct in portmaster, where pdb=/var/db/pkg, 
origin is set to the origin of a given port, and ro_opd is usually 
empty, but can be another origin directory or the same one. To 
guarantee that you should get some kind of results you can test with 
origin=devel/gettext.

egrep -l "DEPORIGIN:($origin|$ro_opd)$" $pdb/*/+CONTENTS

Obviously this works in portmaster with the gnu grep, but if ro_opd is 
unset with the bsd grep I get:

egrep: empty (sub)expression

If I set ro_opd to something, it works.


hth,

Doug
