Curl status code does not match 'last' status when using 102 'Processing' in interim

From: Alex Shaver via curl-library <curl-library_at_cool.haxx.se>

I have a server I connect to that may return one or more 102 'processing'
messages to keep the connection alive while a long processing action is
underway. Supposing the final message is a 200 response, when I check the
curl status code, it returns 102 as the status.

I first noticed this while using pycurl, but I also tested using the curl
command line tool, and got the same result. Fortunately, I can register a
header callback and just manually parse the statuses myself. But this
appears to be a bug as `CURLINFO_RESPONSE_CODE` is documented as returning
the 'last' response code. Granted, the 'last' in that phrase may simply
mean to the most recent 'request/response' process it ran, but it still
feels like it could be improved. Or I may be misusing the tool. Advice on
how to do it correctly would be appreciated, if it is not an error.

Thanks,
Alex
