I hadn't seen today's discussion until after Steve replied to this
patch. Mine is based on your next branch, building upon Steve's patch.

These changes here are somewhat different, in that color is enabled
only if color is available in the terminal in the first place! And if
the standard output is redirected to a file (which is what Masami
reported today), then colors are avoided even if available.

Greetings!
