Hi Junio, [and welcome back, at least I hope you only read this after a good and relaxing vacation]

Note that I also had to change the check_auto_color() function, and while want_color_fd() can have a "private" record of previous results, check_auto_color() needs to use the global color_stdout_is_tty (so that builtin/config.c can edit it, for use in `git config --colorbool <name> [stdout-is-tty]`). > We should honor configuration at two levels, just like the colors on > stdout, i.e. color in which individual items are painted (e.g. > color.diff.filename, color.advice.hint) and whether we use colors in > UI at all (e.g. color.ui). This is how v2 does it. Thanks for your suggestions, Dscho
