New description:

 As part of the effort to reduce the number of dependencies of `wget`, it
 is proposed to make metalink support in `wget` optional via a variant.

 Currently, `wget` is the only dependent on `libmetalink`, and according to
 [https://trac.macports.org/ticket/69601#comment:34 this comment] metalink
 support is disabled on most Linux distributions anyway (in `wget` and
 `curl`), so I'm hoping that there are no ports that indirectly depend on
 `get` having metalink support.
