docs/libcurl/opts: clarify the return values
Expand a little.

- mention the type name of the return code
- avoid stating which exact return codes that might be returned, as that
  varies over time, builds and conditions
- avoid stating some always return OK
- refer to the manpage documenting all the return codes

# NAME
CURLOPT_PROXY_TLSAUTH_USERNAME - username to use for proxy TLS authentication
# SYNOPSIS
~~~c
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXY_TLSAUTH_USERNAME,
char *user);
~~~
# DESCRIPTION
Pass a char pointer as parameter, which should point to the null-terminated
username to use for the HTTPS proxy TLS authentication method specified with
the CURLOPT_PROXY_TLSAUTH_TYPE(3) option. Requires that the
CURLOPT_PROXY_TLSAUTH_PASSWORD(3) option also be set.
The application does not have to keep the string around after setting this
option.
Using this option multiple times makes the last set string override the
previous ones. Set it to NULL to disable its use again.
# DEFAULT
NULL
# %PROTOCOLS%
# EXAMPLE
~~~c
int main(void)
{
CURL *curl = curl_easy_init();
if(curl) {
CURLcode res;
curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
curl_easy_setopt(curl, CURLOPT_PROXY, "https://proxy");
curl_easy_setopt(curl, CURLOPT_PROXY_TLSAUTH_TYPE, "SRP");
curl_easy_setopt(curl, CURLOPT_PROXY_TLSAUTH_USERNAME, "user");
curl_easy_setopt(curl, CURLOPT_PROXY_TLSAUTH_PASSWORD, "secret");
res = curl_easy_perform(curl);
curl_easy_cleanup(curl);
}
}
