Yes. I think you're right. The Curl_do() function simply does some assumptions
that might not always be correct.

In fact, since this Curl_retry_request() function is called when Transfer()
fails (in transfer.c) and then does the necessary attempt-to-start-over magic,
I wonder if perhaps that retry logic in Curl_do() is entirely superfluous... I
fear that we don't have any very reliable test cases for those checks so it'll
be hard to tell exactly.
