Ignore package-conflicts, when none of the "problematic" files actually exist

[UnitedMarsupials]

It would seem reasonable, that, when the conflicting files do not actually exist on the filesystem, the installation should not fail. Instead of seeking, how to modify pkg's command line to "force" the installation, it may be easier to just delete the few problematic entries (when there are only a few, that is).

The below patch may be incomplete -- the same method may need extending to the config-files and directories -- but gives an idea, of what I mean...

In that circumstances would this be the case?

In what circumstances would this be the case?

One example is when a family of related ports is rearranged, and trying to portupgrade them causes conflicts. Such as the multimedia/gstreamer1-plugins-ugly used to install a shared object, which is now provided by the multimedia/gstreamer1-plugins-bad...
