Subject: setopt: let CURLOPT_ECH set to NULL reset to default
X-Git-Tag: curl-8_10_0~147
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=05609bac95709beb387e5273ca33a6054bc89b0b;p=thirdparty%2Fcurl.git

setopt: let CURLOPT_ECH set to NULL reset to default

Because NULL is documented as default and most options that take
pointers accept NULL to reset back to internal default.

Closes #14634
