On Windows, some Windows 10 builds support only ANSI output, but not input, so these need to be separated. I'm also improving the detection on Mac and Linux to avoid hardcoding the result. Instead, supportsAnsiEscapes will be true if isatty() and the TERM environment variable contains the string 'xterm'. related #28614 R=lrn@google.com Review-Url: https://codereview.chromium.org/2753233002 .
