man pages: require all to use the same section header order
This is the same order we already enforce among the options' man pages:
consistency is good. Add lots of previously missing examples.

Adjust the manpage-syntax script for this purpose, used in test 1173.

Closes #7904

.TH curl_mime_subparts 3 "22 August 2017" "libcurl 7.56.0" "libcurl Manual"
.SH NAME
curl_mime_subparts - set subparts of a multipart mime part
.SH SYNOPSIS
.B #include <curl/curl.h>
.sp
.BI "CURLcode curl_mime_subparts(curl_mimepart * " part ,
.BI "curl_mime * " subparts ");"
.ad
.SH DESCRIPTION
\fIcurl_mime_subparts(3)\fP sets a multipart mime part's content from a mime
structure.
\fIpart\fP is a handle to the multipart part.
\fIsubparts\fP is a mime structure handle holding the subparts. After
\fIcurl_mime_subparts\fP succeeds, the mime structure handle belongs to the
multipart part and must not be freed explicitly. It may however be updated by
subsequent calls to mime API functions.
Setting a part's contents twice is valid: only the value set by the last call
is retained. It is possible to unassign previous part's contents by setting
\fIsubparts\fP to NULL.
.SH EXAMPLE
.nf
/* The inline part is an alternative proposing the html and the text
versions of the e-mail. */
alt = curl_mime_init(curl);
/* HTML message. */
part = curl_mime_addpart(alt);
curl_mime_data(part, inline_html, CURL_ZERO_TERMINATED);
curl_mime_type(part, "text/html");
/* Text message. */
part = curl_mime_addpart(alt);
curl_mime_data(part, inline_text, CURL_ZERO_TERMINATED);
/* Create the inline part. */
part = curl_mime_addpart(mime);
curl_mime_subparts(part, alt);
curl_mime_type(part, "multipart/alternative");
slist = curl_slist_append(NULL, "Content-Disposition: inline");
curl_mime_headers(part, slist, 1);
