Here is one of the two.  There is only one NEEDSWORK, not "at both".

	Leave a NEEDSWORK comment at remote.c:handle_config() that
	has a defect similar to what is fixed by this patch, so ...

should be sufficient.

Another is that 

        int cmd_fetch(int argc,
                      const char **argv,
                      const char *prefix,
                      struct repository *repo UNUSED)
        {
                struct fetch_config config = {
                        .display_format = DISPLAY_FORMAT_FULL,
                        .follow_remote_head_raw = NULL,
                        .follow_remote_head_seen = 0,
                        .prune = -1,
                        .prune_tags = -1,
                        .show_forced_updates = 1,
                        .recurse_submodules = RECURSE_SUBMODULES_DEFAULT,
                        .parallel = 1,
                        .submodule_fetch_jobs = -1,
                };

will hold onto a copy of config.follow_remote_head_seen that was
read from the configuration and never frees it, so when cmd_fetch()
leaves, it technically leaks a string.

Other than these two points, this round looks very good.

Thanks.
