Yes. 

However, I think that 90% of the code for the ".." and "..." case are the 
same, as is largely the finding of it.

So why not just do this all inside the already existing

	dotdot = strstr(arg, "..");
	if (dotdot) {
		unsigned char other_sha1[20];
		const char *one = arg;
		const char *two = arg + 2;
		int symmetric = *two == '.';

		*dotdot = '\0';
		two += symmetric;

		if (one == arg)
			one = "HEAD";
		if (!*two)
			two = "HEAD";
		...

because the only difference is really at the very end.

Did you test that it looks correct too?
