This is no bug here. It's just storing the fact that it preserved these
/lib64/libreadline.so.6{,.3} under the replacing newer version package.
That is, readline-7.0_p3 now owns these files, but based on this
registry, they will be deleted and removed from its CONTENTS, once
there are no more consumers of it based on essentially NEEDED.ELF.2
contents in the VDB (/var/db/pkg/*/*/NEEDED.ELF.2).
That is, what is keeping them from being removed is not stored in this
registry.

Maybe there is just an old ruby:2.1 SLOT installed, that hasn't been
properly depcleaned?
