Tells curl to request specific curves to use during SSL session establishment
according to RFC 8422, 5.1. Multiple algorithms can be provided by separating
them with ":" (e.g. "X25519:P-521"). The parameter is available identically
in the "openssl s_client/s_server" utilities.
--curves allows a OpenSSL powered curl to make SSL-connections with exactly
the (EC) curve requested by the client, avoiding nontransparent client/server
negotiations.
If this option is set, the default curves list built into openssl will be
ignored.
