That's not quite it, though. "var" is really the current program's idea of whether color has been requested. So it's git_config_colorbool(), as modified by things like "--color". I think the best explanation is that it resolves an "enum color_bool" into a single 0/1 boolean. Except that "enum color_bool" doesn't exist, so we have no name for it. -Peff
