URL formatter treats release/archive URLs as valid even though they're not supported

[PeterDaveHello]

Though the url formatter support url like this:
https://github.com/rgrove/rawgit/archive/master.zip

but, both of these urls return 404 not found:
https://rawgit.com/rgrove/rawgit/archive/master.zip
https://cdn.rawgit.com/rgrove/rawgit/archive/master.zip

Is it possible to support release/archive tarball? It'll be very nice!

BTW, thanks for this cool service!

It think it goes hand in hand with this feature request: #66

My application master branch magically works fine through rawgit happily:
https://cdn.rawgit.com/hcchengithub/jeforth.3we/master/index.html

But releases
https://github.com/hcchengithub/jeforth.3we/releases/tag/R1
gets "404 error"
https://cdn.rawgit.com/hcchengithub/jeforth.3we/releases/tag/R1/index.html
I don't know if the above URL is correct?
