Yeah, I meant the output of 'rpm -qi'. It would be great to make
it simply skip the line instead of showing "Group       : Unspecified",
but only when %GROUP is really "Unspecified". AFAICS, rpm does not have
a syntax for this, but of course the syntax is helpfully completely
undocumented, so it's hard to say for sure.

Patching ~/.popt is an option, but I would prefer to see Group if it
is given.

I filed https://github.com/rpm-software-management/rpm/pull/532 for the Relocations: line.
