Re: [PATCH 1/2] notes.c: fix a segfault in notes_display_config()

nate@roosteregg.cc writes:

 	if (*load_refs && !strcmp(k, "notes.displayref")) {
 		if (!v)
-			config_error_nonbool(k);
+			return config_error_nonbool(k);

"git grep config_error_nonbool" tells us that this is the only
instance that ignores the return value from the function and does
not cause the caller to die.

Looks good.  Thanks.
