    build: Rebuild man pages when 'configure.ac' changes.
    
    Fixes <https://bugs.gnu.org/39694>.
    Reported by Efraim Flashner <address@hidden>.
    
    This ensures that man pages are rebuilt when the version number is
    changed in 'configure.ac'.
    
    * Makefile.am (doc/shepherd.1, doc/%.1, doc/%.8): Add dependency on
    'configure.ac'.
