If I remember correctly, then the shell version prints the output in case
of an error.

We already imitated that behavior in `git commit`
(https://github.com/git-for-windows/git/blob/v2.13.0.windows.1/sequencer.c#L674-L684):

		/* hide stderr on success */
		struct strbuf buf = STRBUF_INIT;
		int rc = pipe_command(&cmd,
				      NULL, 0,
				      /* stdout is already redirected */
				      NULL, 0,
				      &buf, 0);
		if (rc)
			fputs(buf.buf, stderr);
		strbuf_release(&buf);

I think that would be the appropriate approach here, too.

Ciao,
Johannes

P.S.: it may be a very good idea to accompany this patch (as well as the
previous one) by a patch to the test suite to verify that the fixed code
does not regress.
