Gist filename case on https.get()'s url

[woolninesun]

If Gist filename is ABC.js
The url is "https://gist.github.com/<github_id>/<gist_id>#file-abc-js"
The https.get()'s url is "https://gist.github.com/<github_id>/<gist_id>.js?file=abc.js"

But it will get statusCode: 404 because filename case wrong!
url need to be "https://gist.github.com/<github_id>/<gist_id>#file-ABC-js"

maybe can warn user to care about this and add some output to warn user if get 404 statusCode

Sorry about my poor english
