    Merge branch 'master' into ng/master

    * master:
      tests: avoid non-textual output in a '.log' file
      tags: refactor to reduce code duplication (2)
      tags: refactor to reduce code duplication (1)
      tests: better name for a couple of tests
      check: support colorized testsuite output by default
      tags: unify recursion for tags targets with that of "usual" targets

    + Extra non-trivial edits:

    * automake.in (handle_tests): Drop the '%COLOR%' transform in the
    processing of both 'serial-tests.am' and 'parallel-tests.am', which
    have superseded the 'check.am' from mainline Automake.
    * lib/am/color-tests.am: Remove use of the '%?COLOR%' transform;
    just act as if it were unconditionally TRUE.
    (am__tty_colors_dummy): Merge into ...
    (am__tty_colors): ... this.
