leaving behind .sample files and pkg_add alternate registerdb

And another gotcha, I have a difference in pkg-plist behaviour between
make install/deinstall and pkg_add/delete

3) Is it possible that pkg_create doesn't add/create empty directories?
(I copied an example dir from a src archive, and it had empty CVS/ dirs
in it)
