Bug 15162

	I thought it would be useful to limit the output of pkg_version
	to one or more matching status flags.  The attached patch
	implements this option.

	In particular, this lets get the commands to update merely the
	out of date ports with ease:

	% pkg_version -c -l '<'
#
#  less
#  needs updating (index has 340)
#
cd /usr/ports/misc/less
make
pkg_delete -f less-337
make install

#
#  vim
#  needs updating (index has 5.5.38)
#
cd /usr/ports/editors/vim5
make
pkg_delete -f vim-5.5.37
make install

Fix: Here's the patch:
