Last time I tried it, pkg_add -r -K did indeed save local copies of
the packages fetched from the remote repository, but a problem arose
when one later wanted to _use_ that local stash while falling back to
-r behavior for anything not found locally.  Last I knew there was no
easy way to tell pkg_add to do that.
