So "pkg_info -F" lists all files and the pkgs they belong to?
Incidentally, that's how it work - i just didn't include it in the
miyu# ./pkg_info -F

it's probably not for two reasons:
1. +CONTENTS doesn't store full pathnames
2. accessing the db-file is much faster than expanding the * and then
grep through all these files:
miyu# time grep etc/revision-history /var/db/pkg/*/+CONTENTS
0.014u 0.225s 0:08.58 2.6% 0+0k 462+69io 13pf+0w
miyu# time ./pkg_info -Fe /emul/linux/etc/revision-history
0.015u 0.000s 0:00.01 100.0% 0+0k 0+0io 0pf+0w
That's um... factor 800?

That's how things work without the pkgdb, why should they suddenly change
just because the -F switch is given? I don't see any real reason here.
