One change, multiple ports

Hi Takeshi! A little committer's hint: changes like the ones you just made to your ports to reflect your new maintainer address, it's perfectly acceptable to do all of them, spanning all affected ports, in a single commit. Our general rule reads "one logical change, one commit", and when it comes to Portfiles that usually maps to a single one. However, when the one logical change is something that affects multiple Portfiles on an equal basis (extra emphasis on this condition!), it's perfectly acceptable to commit all of them together. Other than that, welcome aboard! Regards,... -jmpp
