Is there any reason that we need to have this variable's value to be "int"? I _think_ in this patch, the variable is used to choose between the default and "HTTP/2", and I do not think the updated code can choose any other new value that may be supported by an even newer cURL library without further update, i.e. we'd need a variant of "if the configuration asks HTTP/2 then use CURLOPT_HTTP_VERSION with CURL_HTTP_VERSION_2" for the new choice.
So I'd think it would not add much value to force end users use a rather cryptic "20" (vs "11") to choose between "2" and "1.1". Why not use spell it out, e.g. using the official name of the protocol "HTTP/2" (vs "HTTP/1.1"), with a "const char *" instead?
The new configuration variable and the possible values it can take must be documented, of course. I think it would make the description far less embarrassing if we say "HTTP/2" etc. rather than "20", "11", etc.

Shouldn't this block also handle the other values, e.g. "11"?
I _think_ the curl_http_version variable (be it an deci-int, or a const char *) should be initialized to a value that you can use to notice that the configuration did not specify any, and then this part should become more like
if (curl_http_version &&
!get_curl_http_version_opt(curl_http_version, &opt))
curl_easy_setopt(result, CURL_HTTP_VERSION, opt);
with a helper function like this:
static int get_curl_http_version_opt(const char *version_string, long *opt)
{
int i;
static struct {
const char *name;
lnog opt_token;
} choice[] = {
{ "HTTP/1.1", CURL_HTTP_VERSION_1_1 },
{ "HTTP/2", CURL_HTTP_VERSION_2 },
}; for (i = 0; i < ARRAY_SIZE(choice); i++) {
if (!strcmp(version_string, choice[i].name)) {
*opt = choice[i].opt_token;
return 0;
}
} return -1; /* not found */
}
which would make it trivial to support new values later.
