Bug#988105: apt-file: could --installed become an (interesting) option?

[Patrice Duroux <patrice.duroux@gmail.com>]

Package: apt-file
Version: 3.2.2
Severity: wishlist

Dear Maintainer,

I don't if this could be possible, interesting and intentionally equivalent:

apt-file --installed search|find <pattern> = dpkg-query -S <pattern>

Thanks,
Patrice
