When the curl command line has an error, the numeric value of the error enum is printed, for example below (35):

curl "https://packages.r-universe.dev"
curl: (35) OpenSSL/3.3.2: error:0A000458:SSL routines::tlsv1 unrecognized name

This is too very informative. We can easily convert this into readable code using curl_easy_option_by_id(x)->name such that we get the string CURLE_SSL_CONNECT_ERROR, which is a bit more informative.

Would it be a suggestion to print the error name (minus the curle_ prefix) such that it would look like:

curl: (ssl_connect_error) OpenSSL/3.3.2: error:0A000458:SSL routines::tlsv1 unrecognized name

curl/libcurl version

curl 8.10.1
