Bug description: dns_get_record() doesn't return all text from TXT record
Description:
------------
dns_get_record() doesn't return all text from TXT record.
RFC 1035 states that TXT record values can't have "compression", but can
have multiple strings for the same DNS record. Although uncommon, such long
TXT strings actualy exist to make publicly available public key data for
DomainKeys e-mail protocols (used by Yahoo! and Gmail).
The following code examples where compiled when under Windows, the command
"nslookup -type=TXT bravo._domainkey.yahoogroups.co.uk" returned:
(...)
Non-authoritative answer:
bravo._domainkey.yahoogroups.co.uk text =
"k=rsa;

"KJQrqcmVSvG7oT3r7Fwo6aCHMMuL+IZdEpbb9ZU8xomQIDAP//"
Reproduce code:
---------------
$x = dns_get_record("bravo._domainkey.yahoogroups.co.uk", DNS_TXT);
