and with %transfiletriggerin this could even be automated from within the info
package. <http://rpm.org/wiki/FileTriggers>

%transfiletriggerin -- %{_infodir}
while read -r file || [ -n "$line" ]; do
    /sbin/install-info "$file" %{_infodir}/dir || :
done

%transfiletriggerpostun -- %{_infodir}
while read -r file || [ -n "$line" ]; do
    /sbin/install-info --delete "$file" %{_infodir}/dir || :
done


And we could just drop all the %post and %preun from the other zillion spec files.
