IMO, you don't need to declare this option as internal; offering it for
the public is fine...

Improved error checking, but quick and dirty:

+	if (!strcmp(argv[1], "--show-strategies")) {
+		for (i = 0; i < ARRAY_SIZE(all_strategy); i++)
+			printf("%s\n", all_strategy[i].name);
+		return argc == 2 ? 0 :
+			 error("--show-strategies does not take "
+				"any arguments");

+	git merge --show-strategies
