help: update the color documentation for Windows 10 ANSI support It looks like only the initial release of Windows 10 lacked support for this functionality. [1][2] Since that build is no longer supported, I didn't bother getting very specific, to keep the help text less cluttered.

color: enable ANSI support on Windows 10 This will display color if "color.mode=ansi", and default to 'ansi' if the mode is set to 'auto'. The 'debugcolor' command also reflects this policy. Previously, "color.mode=ansi" on Windows printed jibberish around the normal text. Using ANSI color is better, as it avoids the normal loss of color when the default pager is enabled on Windows. See also issue5570. When the underlying function fails (e.g. when run on older Windows), 'auto' still falls back to 'win32'. Apparently, Microsoft originally had this feature turned on by default, and then made it opt-in[1]. Therefore, not enabling it unconditionally seems safer. Instead, only do it after processing the existing check for support in a Unix-like environment. [1] https://github.com/symfony/symfony/issues/17499#issuecomment-243481052
