Attempt to fix 'pkg info -E'.

openssl-1.0.1_9
worm:~/src/pkgng:% pkg info -qx ssl
worm:~/src/pkgng:% pkg info -x ssl
openssl-1.0.1_9
worm:~/src/pkgng:% pkg info -Ex foo
pkg: No package(s) matching foo
worm:~/src/pkgng:% pkg info -qx foo
worm:~/src/pkgng:% pkg info -x foo
pkg: No package(s) matching foo
