I'm not talking about the generated file, but the procedure that
generates it.  Special characters like dots and slash are still pretty
special in Scheme, even if they're allowed as identifiers.

I wouldn't do this inside of extract-package-source, but define a one
or two liner for adding specifically packages hosted on racket's
github.  WDYT?

Note that the goal is not to code golf, but to be understandable.  When
adding a bunch of origins as inputs, understandability suffers by
induced scrolling.
