lowdown_buf — parse a Markdown buffer into formatted output

       Parses a lowdown(5) buffer buf of size bufsz into an output buffer ret  of  size  retsz  according  to  a
       configuration  opts.   The  output  format  is  specified  by  opts->type.  If LOWDOWN_METADATA is set in
       opts->feat and metaq is not NULL, metaq is filled with metadata rendered in the given output format.

       The caller is responsible for freeing ret and metaq.

       The  following  parses standard input into a standalone HTML5 document.  It enables footnotes, autolinks,
       tables, superscript, strikethrough, fenced  codeblocks,  commonmark,  definition  lists,  extended  image
       attributes, and metadata processing.  The output passes through raw HTML and has smart typography.

             char rbuf[1024];
             size_t sz, bufsz = 0, obufsz;

             while (!(feof(stdin) || ferror(stdin))) {
                     sz = fread(rbuf, 1, sizeof(rbuf), stdin);
                     if (sz == 0)
                             err(1, "fread");
                     buf = realloc(buf, bufsz + sz);

                             err(1, NULL);
                     memcpy(buf + bufsz, rbuf, sz);
