Correct. It reads the entire config file first, then performs.

If you think about it further, you realize it isn't possible. The options read
on the command line and config file are all considered, and their individual
order is mostly not important. It means that the entire config file needs to
be read first to get to know all the command line options that are used.

Also, the curl tool is not multi-threaded interally anyway and uses the
curl_easy_perform() function to do its transfers so it really cannot read from
any file like that while also transferring data so even if there would be a
separate option for this, it would be restricted - or require a larger
architectural rewrite to makae curl use the multi interface.
