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 CURLINFO_NUM_CONNECTS 3 "12 Sep 2015" "libcurl 7.44.0" "curl_easy_getinfo options"
.SH NAME
CURLINFO_NUM_CONNECTS \- get number of created connections
.SH SYNOPSIS
.nf
#include <curl/curl.h>
CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_NUM_CONNECTS, long *nump);
.fi
.SH DESCRIPTION
Pass a pointer to a long to receive how many new connections libcurl had to
create to achieve the previous transfer (only the successful connects are
counted). Combined with \fICURLINFO_REDIRECT_COUNT(3)\fP you are able to know
how many times libcurl successfully reused existing connection(s) or not. See
the connection options of \fIcurl_easy_setopt(3)\fP to see how libcurl tries
to make persistent connections to save time.

res = curl_easy_perform(curl);
if(res == CURLE_OK) {
