Heh...

The test of the function has these cases:

static void check(const char *cwd, const char *path, const char *good);

int main(int argc, char **argv)
{
	/* 1 */ check("/onelevel", "aa", "onelevel/aa");
	/* 2 */ check("/", "..", "");
	/* 3 */ check("/", "../..", "");
	/* 4 */ check("/one", "aa/../bb", "one/bb");
	/* 5 */ check("/one/two", "aa//bb", "one/two/aa/bb");
	/* 6 */ check("", "/aa//bb", "aa/bb");
	/* 7 */ check("/one/two", "", "one/two");
	/* 8 */ check("/one/two", "aa/..bb/x/../cc/", "one/two/aa/..bb/cc");
	/* 9 */ check("/one/two", "aa/x/././cc////", "one/two/aa/x/cc");
	/* 10 */ check("/one/two", "../../../../aa", "aa");
	/* 11 */ check("one/", "../one/two", "one/two");
	/* 12 */ check("", "../../two", "two");
	/* 13 */ check("a/b/c", "../../two", "a/two");
	/* 14 */ check("a/b/", "../two", "a/two");
	/* 15 */ check("///", "../two", "two");
	return 0;
}

static void check(const char *cwd, const char *path, const char *good)
{
	static int n = 0;
	printf("%-2d: %10s$ cd %s", ++n, cwd, path);
	char *t = pathexpand(cwd, path);
	if ( strcmp(t, good) )
		printf(" ____________________failed(%s)\n", t);
	else
		printf(" \033[32m%s\033[0m\n", t);
	free(t);
}
