    [Pod::Man] Avoid undefined variable warnings when determining the
    title for a Perl module at the top level of a distribution.  Thanks,
    Dave Mitchell.  (#112625)

    [Pod::Man] Fix font resets with nroff when fixed-width fonts are used
    in the label for an =item.  Previously, italic was being ended with
    \f(CW even in nroff mode, which, with groff, only changes the font to
    fixed-width and doesn't reset to a non-italic font.  Thanks, Paul
    Townsend.  (#98199)

    [Pod::Man] Suppress warnings about a missing Encode module if
    PERL_CORE is set in the environment.  Due to build ordering during
    Perl core builds, Encode is expected to not yet be available during
    the build step that sets PERL_CORE.  Thanks, Dave Mitchell.
