A bit of experimenting with BIND and reading the zone file syntax
in rfc1035 can explain what probably happened. All entries below are
syntactically correct as far as the zone syntax and DNS is concerned.

right._domainkey  TXT  ("k=rsa; p=MIG"
                        "MAG0udE82Yzb7"
                        "xLv4QnQIDAQAB")

wrong._domainkey  TXT   "k=rsa; p=MIG\
MAG0udE82Yzb7\
xLv4QnQIDAQAB"

wrong2._domainkey TXT  "k=rsa; p=MIG\013\010MAG0udE82Yzb7xLv4QnQIDAQAB"
