[Bro] arp_main.bro : hexa code in arp_states result

[Nicolas KRASINSKI]

Hello, 

In the arp_main.bro script ( https://gist.github.com/grigorescu/a28b814a8fb626e2a7b4715d278198aa ), the global " arp_states " give this weird result : 

[mac_addr=00:2c:7h:40:55:55, ip_addr=192.82.180.62, assoc_ips= { \x0a\x09 192.168.3.254, \x0a\x09 192.168.1.254, \x0a\x09 195.83.180.62, \x0a\x09 192.168.2.254 \x0a }, requests={ \x0a\x0a }] 


The part of arp_main script with the global arp_states : 

---------------------- 
type State: record { 
mac_addr: string; 
ip_addr: addr; 
assoc_ips : set[addr]; 
requests : table[string, addr, addr] of Info 
&create_expire = 1 min 
&expire_func = expired_request; 
}; 
global arp_states: table[string] of State; 
-------------------- 

The " assoc_ips" is set[addr] and requests is table , so I don't understand why I have hexa code (x0a = line feed, x09 = horizontal tab) in the result ? 

Thank you for your help, 

Best regard, 

Nicolas KRASINSKI.
