Comment(by ryandesign@…):

 I attached a revised update proposal, which differs from your patch in
 that it removes the revision line (because the first revision of any given
 version of a port should be 0), removes the md5 checksum (because md5 is
 an obsolete checksum algorithm which I would like to eventually remove
 from MacPorts), and observes the whitespace conventions of the portfile
 (spaces not tabs).

 The reason I'm not committing it yet is that the library version of both
 libraries has increased from 26 to 27, which means that all ports that use
 (or can optionally use) gnutls (and possibly some ports that use ports
 that use gnutls, and so on) must simultaneously have their revisions
 increased to force a rebuild against the new library, and I haven't yet
 tried to identify what all those ports are, but there are probably a lot.
