I also thought about marking default variants some time ago, but I think 
this should not only be added to port variants, but also to port info. 
Where the latter will be more difficult, as default_variants are 
currently not stored in PortIndex.

It would be good to e.g. mark them with a star.
     git-core 1.5.3.7, devel/git-core (Variants: universal, *doc, svn)

And this could also be used for port variants.
     git-core has the variants:
             universal
            *doc: Install HTML and plaintext documentation
             svn: Bi-directional subversion repository support

I don't like that (default) behind the description as it is not clear if 
it is part of the description or not.

The star (or another symbol) could also be behind the variants name, 
that's open for discussion. That's why I put this up on macports-dev@ 
instead of adding a comment to the ticket.
