    Merge branch 'master' into ng/master

    * master:
      cleanup: simplify subroutine '&saw_extension'
      cleanup: remove subroutine '&saw_sources_p'
      cleanup: remove unused '&count_files_for_language' subroutine
      automake: simplify '&saw_sources_p'
      tags: look at $(am__tagged_files) to decide whether to activate
      tags: new var $(am__tagged_files) to list all files to run taggers on
      tags (cscope): also process $(TAGS_FILES)
      tags (ID, cscope): also process config header (if any)

    + Extra non-trivial edits:

    * automake.in (handle_tags): Adjust the call to 'define_variable' for
    the variable '$(am__tagged_files)' to the different signature we have
    in Automake-NG, i.e., "define_variable($VAR, $WHERE, @VALUE)" rather
    than "define_variable($VAR, $VALUE, $WHERE)".
