 Right now masterLoad() rejects a zone file even if it was preprocessed
 by named-compilezone if the zone is signed, because it contains an
 in-line comment for DNSKEYs:
 {{{
 example.                                      3600 IN DNSKEY    256 3 7
 AwEAAaetidLzsKWUt4swWR8yu0wPHPiUi8LUsAD0QPWU+wzt89epO6tH
 zkMBVDkC7qphQO2hTY4hHn9npWFRw5BYubE=  ; key id = 40430
 }}}

 Of course, masterLoad() should eventually be more flexible and should
 be able to accept any valid form of zone files. But since it's
 unlikely that we have enough time to do that by the end of y3, I think
 we should at least accept this particular form, even by adding some
 ad-hoc special case handling.
