Description of problem:

In the pre-removal transaction display, the distinction between the "Removing depended packages" and the "Removing unused dependencies" section is unclear

I thought the distinction was between "Packages that depend on packages being removed" and "Packages that were never explicitly installed and no longer have anything depending on them" but that doesn't appear to be the case.

Version-Release number of selected component (if applicable):

dnf-2.6.3-4.fc27.noarch

How reproducible:

Always

Steps to Reproduce:
1. Run "dnf install mc" in a clean F27 container image
2. Run "dnf remove mc" (say "No" at the prompt)
3. Run "dnf remove perl-interpreter" (say "No" at the prompt)


Actual results:

The pre-removal transaction display for the two removal commands is essentially identical, except for which package has been specified for removal.

Expected results:

"Depended packages" should be empty for "mc" (nothing depends on it) and list several modules (including "mc") for "perl-interpreter"

"Unused dependencies" should include all of mc's implicitly installed dependencies for the "mc" case, and list several modules (including "python2") for the "perl-interpreter" case


Additional info:

I don't know if this is a UX bug (i.e. the categories aren't really different or they mean something other than what I though they meant) or a functional bug (with unused dependencies being listed in the wrong section in the pre-removal transaction display).
