Yeah, it uses pretty.c::skip_blank_lines(), which is easy to use.
so something like a loop that calls skip_blank_lines() to see if it
returns a differnt result (which means the argument we fed it was at
the beginning of a blank line, which is what this helper wants to
return), and otherwise we advance by one line with strchrnul() and
retry, perhaps.
while (*body) {
char *next = skip_blank_lines(body);
if (next != body)
break; /* found a blank line */
body = strchrnul(body, '\n');
if (*body)
body++;
}
/* body has the answer */
