On this, and a great many other packages, you've included "github-com-"
in the package names.  I think this is a very bad idea.  For one thing,
we should not advertise, promote, or enhance the lock-in of GitHub, and
this policy does all three.  Sometimes a maintainer decides to change
their hosting arrangements.  When they do so, we should simply be able
to update some URLs in one package definition.  We should not have to do
a global find/replace on the package name and alert our users to update
their profiles and OS definitions.  That contributes to lock-in.

What do you think?
