The diff_opt infrastructure sets flags based on defaults and command line options. It is impossible to tell whether a flag has been set as a default or on explicit request. Update the structure so that this detection is possible: * Add an extra "opt->touched_flags" that keeps track of all the fields that have been touched by DIFF_OPT_SET and DIFF_OPT_CLR. * You may continue setting the default values to the flags, like commands in the "log" family do in cmd_log_init_defaults(), but after you finished setting the defaults, you clear the touched_flags field; * And then you let the usual callchain call diff_opt_parse(), allowing the opt->flags be set or unset, while keeping track of which bits the user touched; * There is an optional callback "opt->set_default" that is called at the very beginning to let you inspect touched_flags and update opt->flags appropriately, before the remainder of the diffcore machinery is set up, taking the opt->flags value into account.
