Duplicate documentation files have been detected in the package
builds for Rawhide and Fedora 20. The likely cause is the unversioned
docdirs change in Fedora 20.

If your package %installs documentation files into %{_docdir}/%{name}/ to
store them in a subpackage, this now conflicts with using the %doc
macro in the base package. Since Fedora 20, the %doc macro installs into
the unversioned %{_docdir}/%{name}/ and includes everything in that
directory. One obvious fix is to decide between either using %doc or
installing into %{_docdir}/%{name}/ manually as explained in the
Packaging tricks Wiki section (for past dist releases and the versioned
docdir).
