I've modeled them after -x and -e:

pkg_info -x -> regular expressions, pkg_info -X -> exended regular expressions

pkg_info -e -> test if a package is installed, pkg_info -E -> test if installed packages are matched by a glob pattern (and display the matched names).

To achieve the latter bsd.port.mk currently does `ls -d /var/db/pkg/PATTERN 2>/dev/null'.

The pkg_* tools have a plethora of inconsistent knobs, but they are mainly used in scripts. I don't really care, but I already use -E in portaudit, so do you think it is really worth the effort? Of
course I *can* check the version number, so switching the flags is possible.
