HTTPS warning on developer.r-project.org

[Please CC me on replies, as I am not subscribed.]

Dear R folks,


Accessing the *R Developer Page* [1], the browser (Firefox) shows an 
HTTPS warning.

The reason is the embedded Google logo.

Gemischte (unsichere) Anzeige-Inhalte von "http://www.google.com/logos/Logo_40wht.gif" werden auf einer sicheren Seite geladen

Could you change that to an HTTPS link please?

```
$ curl -I https://www.google.com/logos/Logo_40wht.gif
HTTP/2 200
