A longer term issue probably, but I think the entire concept of output
intended for humans during package installation no longer makes sense,
given the prevalance of automated package tools.  I think we should
instead be moving to a way to ask about a package.  Plus, I think we
should expect users to read upstream documentation to configure, and not
reinvent that in pkgsrc.

As for no-longer-needed config files, perhaps instead there should be a
pkg_admin or some such to list config files that were installed by
pkgsrc and are no longer claimed by an installed package.   Cleaning up
and de-installing are not necessarily linked in time.
