  color-tests: coloring can be forced on non-ANSI terminals as well
  
  Before this change, colorization of testsuite output was suppressed
  whenever the terminal was recognized to be a "dumb" one, incapable
  of handling ANSI coloring (i.e., when the environment variable TERM
  had a value of "dumb").  This happened even when the AM_COLOR_TESTS
  variable was set to a value of "always".
  
  Such a behaviour was suboptimal and slightly confusing; in fact, if
  a user wants to force coloring of testsuite output that is being
  redirected to a regular file, he should be able to do so even if his
  terminal is not capable of handling ANSI colors -- in fact, such
  terminal wouldn't be involved with the testsuite output in any way,
  so why should it be allowed to influence it?
  
  Thus, we now enable coloring of test output whenever AM_COLOR_TESTS
  is set to "always", irrespective of the value of the TERM environment
  variable.
  
  * NEWS: Update.
  * lib/am/check.am [%?COLOR%] (am__tty_colors): Activate colorization
  of testsuite output whenever AM_COLOR_TESTS has the value of "always".
  * t/ax/tap-summary-aux.sh: Export the TERM environment variable to
  "dumb" when forcing colorization of the testsuite output; this should
  *not* prevent such colorization from taking place, and we want to
  check that this expectation really holds.
  * t/ax/testsuite-summary-checks.sh: Likewise.
  * t/color.sh: Likewise, and adjust some grepping checks.
  * t/tap-color.sh: Likewise.  Also, remove redundant "make check"
  invocation since we are at it.
  * t/color2.sh: Likewise, and check that exporting TERM=dumb actually
  prevents testsuite output colorization when AM_COLOR_TESTS is unset.
  * t/parallel-tests-reset-term.sh: Relax, to prevent it from failing
  spuriously due to the new semantic.
