Hi alls,

We are used to trace the libcurl output to a file for troubleshooting of our setup and libcurl
problems, if any, using customized tracing function similar to docs/examples/debug.c my_trace.

The tracing output may be rather large and to figure out the errors we are using the following patch,
which may be useful for community as well. In brief the patch calls spades the spades and places CURLINFO_ERROR
curl_infotype on errors to mark them for futher searches.
