Yes, I'm aware that my suggestion is somewhat redundant and
"advanced" from libcurl's point of view. I was looking
to reduce the application complexity with a simple hack
in libcurl. When in a curl_multi environment with many
concurrent downloads, having the redirect callback
is handy, as I can continue to use FOLLOWLOCATION (without
redirect limit) without adding my own application logic and
still be compliant with robots.txt. Reading CURLINFO_REDIRECT_URL
would be too late for that purpose as the url is already fetched
when that info is available.

Anyway, maybe the patch is useful for somebody with the same
problem.
