Long TXT records don't get splitted

[Andre Schild]

DKIM TXT records can have a length of more than 255 characters.

The ldap2dns utility does create one very long line with all the content in it.

google._domainkey TXT "v=DKIM1; k=rsa; p=MIIBIjANBgkqh......."

Bind9 is restricting the entries on one line to 255 characterts, so it needs to be split up in multiple lines with max 255 characters.

A correct output would be:

google._domainkey TXT ("v=DKIM1; k=rsa; p=MIIBIjANB.....CsA793sVyehx"
                                         "Sy7XE21Mv+gD1VgKmOXvSrDLMl1.....iUbMAEQcnRrN"
                                         "5omtqs5fVl4mZZ23yr/1nHryV5k.....duNRwL5+char"
                                         "0Zd0ft17ekhxqeG85zdPvyk7v1k.....Y1BaFisnb/u6"
                                         "mxJQEVOwIDAQAB")
