I force-pushed (see https://github.com/gitgitgadget/git/pull/400), and
once Stolee approves, he will submit v3. This will only change the
commit message, though, as I disagree that hard-coding the URL would be
an improvement: the nice thing about a package management system is that
the user does not need to know the details (or need to know if the
details change, like, ever).

Ciao,
