Stream proxy ptotocol header is not valid

[zdm@…]

Nginx sends proxy protocol header without triling "\r\n" when unix socket path is too long,

Sample config:

`
strema {

server {

listen *.80;
proxy_pass unix:/var/run/1.socket;
proxy_protocol on;

}

server {

listen unix:/var/run/1.socket prtoxy_protocol;
proxy_pass 127.0.0.1:8080;
proxy_protocol on;

}

}

`

When send simple HTTP GET request to :80 - it;s ok;

But when socket oath is ontr, than 80 chars - nginx sends data like this ( WITHOUT "\r\n" separator after proxy protocol header ):

`
PROXY TCP 1.2.3.4 unix:.... pott1 port2GET
