Summary: Problem downloading 2 zero byte files with FTP

Initial Comment:
Hi,

When downloading 2 zero byte files in a row, curl 7.16.0 enters an infinite loop, while curl 7.16.1-20061218 does one additional unnecessary request.

I tracked this problem to the variable headerbytecount being 0 in Curl_retry_request function. This used to be a number bigger than zero in curl-7.15.5 and older. Here is a simple program that will trigger this problem:

#include <curl/curl.h>
#include <curl/easy.h>

int main() {
  CURLcode curl_res;
  CURL* easy;

  curl_global_init(CURL_GLOBAL_ALL);
  easy = curl_easy_init();
  curl_easy_setopt(easy, CURLOPT_VERBOSE, 1);
  curl_easy_setopt(easy, CURLOPT_URL, "ftp://ftp.sunet.se/pub/Linux/funet/sunsite_is_now_metalab_under_mirrors");

  curl_res = curl_easy_perform(easy);

  curl_res = curl_easy_perform(easy);

  return 0;
}
