ngx_cpystrn() description say that function "Copies information from one memory location to another. Stops when n bytes are copied" (https://www.nginx.com/resources/wiki/extending/api/utility/)
But in fact it copies n-1 byte(src/core/ngx_string.c):
"
while (--n) {
*dst = *src;
"
Please, fix (documentation).
