Interesting.

Suppose I configure

	[url "git://anongit.myserver.example.com/"]
		insteadOf = myserver.example.com:
	[url "myserver:"]
		pushInsteadOf = myserver.example.com:

The above code would make the insteadOf rule apply instead of
pushInsteadOf, even when pushing.  Perhaps something like the
following would work?

			const char *url = remotes[i]->pushurl[j];
			remotes[i]->pushurl[j] = alias_url(url, &rewrites_push);
			if (remotes[i]->pushurl[j] == url)
				/* No url.*.pushinsteadof configuration matched. */
				remotes[i]->pushurl[j] = alias_url(url, &rewrites);

Looks good.  The usual style in git tests is to include no space
after >redirection operators:

		git for-each-ref refs/remotes/origin >actual &&

Hope that helps,
