Upstream changes:
2019-03-19  k  <andk@cpan.org>

        * release 2.26

        * testfix release, no functional change

        * 97-run.t is now skipped when test is run by root user because
        perldoc often fails for root user (thanks to Binarus for
        reporting)

        * small additions to distroprefs and to the Makefile.PL
