docs: consistent manpage SYNOPSIS
Make all libcurl related options use .nf (no fill) for the SYNOPSIS
section - for consistent look. roffit then renders that section using
<pre> (monospace font) in html for the website.

Extended manpage-syntax (test 1173) with a basic check for it.

Closes #8062

.TH CURLOPT_DNS_LOCAL_IP6 3 "19 Jun 2014" "libcurl 7.37.0" "curl_easy_setopt options"
.SH NAME
CURLOPT_DNS_LOCAL_IP6 \- IPv6 address to bind DNS resolves to
.SH SYNOPSIS
.nf
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_DNS_LOCAL_IP6, char *address);
.fi
.SH DESCRIPTION
Set the local IPv6 \fIaddress\fP that the resolver should bind to. The
argument should be of type char * and contain a single IPv6 address as a
string. Set this option to NULL to use the default setting (do not bind to a
specific IP address).
The application does not have to keep the string around after setting this
option.
.SH DEFAULT
NULL
.SH PROTOCOLS
All
.SH EXAMPLE
.nf
CURL *curl = curl_easy_init();
if(curl) {
curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/foo.bin");
curl_easy_setopt(curl, CURLOPT_DNS_LOCAL_IP6, "fe80::a9ff:fe46:b619");
ret = curl_easy_perform(curl);
curl_easy_cleanup(curl);
}
.fi
.SH AVAILABILITY
This option requires that libcurl was built with a resolver backend that
supports this operation. The c-ares backend is the only such one.
Added in 7.33.0
.SH RETURN VALUE
Returns CURLE_OK if the option is supported, CURLE_UNKNOWN_OPTION if not,
CURLE_NOT_BUILT_IN if support was disabled at compile-time, or
CURLE_BAD_FUNCTION_ARGUMENT when given a bad address.
