Thank you Frederick on the notes and explanations of using the -F switch.

I was hoping for a quick tool for looking for a filename without full
path (or even a partial filename) that returns the package(s) it is a part
of.

Grepping "pkg_admin dump" is a few seconds faster than grepping the
/var/db/pkg/*/+CONTENTS files, but it doesn't return as much -- probably
because I need to do "pkg_admin rebuild".
