Subject: Use variable for diff options instead of unconditionally specifying "-rN".
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=69d7fcb105738c33ad53326628c1c1d8d567b36a;p=openbsd

Use variable for diff options instead of unconditionally specifying "-rN".
This will make life easier in -portable where not all diff's understand -N.
