Nice, applied!

I think the whole point of having the ‘%github-api’ parameter is that it
allows us to mock the HTTP server instead of having to override bindings
such as ‘http-fetch’.

I’d have a slight preference for doing that, similar to what is done in
tests/cpan.scm for instance.  WDYT?

Thanks,
Ludo’.
