[PATCH 2/2] remote-curl.c: handle v1 when check_smart_http

[lilinchao@oschina.cn]

From: lilinchao <lilinchao@oschina.cn>

When clone with http protocol version 1, the server side
just tells client that "invalid server response, got version 1",
this is not clear enough, because version 0 is ok, and
version 2 is ok, then version 1 should be ok too intuitively,
but the other side just treat it as "invalid response", this
can't explain why is not ok.

>From receive-pack/upload-pack, there is a comment which I think,
can explain it:
"v1 is just the original protocol with a version string".
So I made this patch to try to fix it.
