    Merge branch 'master' into ng/master

    * master:
      docs: AM_CFLAGS: remove reference to non-existing "more detailed" desc
      maintcheck: prefer '$(am__cd)' over plain 'cd'
      fetch: improve, and reduce code duplication
      docs: add rule to generate manuals for www.gnu.org
      docs: copy the 'gendocs.sh' script from Texinfo CVS repository
      sync: update files from upstream with "make fetch"
      release: generate a stub for the release announcement
      release: distinguish major and minor releases
      tests: avoid two spurious failures on FreeBSD

    + Extra non-trivial changes:

    * Makefile.am (clean_texinfo_clutter_cmd, clean-web-manuals): Simply
    use "cd" rather than "$(am__cd)".
