How about this (relative to master)?  It fixes your original problem but
retains the separate-sections behaviour for man pages specified by filename.

diff --git a/Completion/Unix/Command/_man b/Completion/Unix/Command/_man
index 41ae85a1f..bee7be410 100644

       for sect_dirname in $sects; do
         d=$sect_dirname

Aside:

    % compdef _f f
    % _f() _files -/
    % f Util/<TAB>
.
offers files, rather than nothing.  Bug?
