Hi --

I just clicked on an old link to http://www.gnu.org/software/diffutils/manual/. Then the web browser showed the address http://www.gnu.org/software/diffutils/manual/ and marked it "insecure". So I tried https://www.gnu.org/software/diffutils/manual/ (with an s) and the browser showed that address.

I'm writing to suggest that you might add a redirect from http://www.gnu.org/software/diffutils/manual/ to https://www.gnu.org/software/diffutils/manual/ so that no one will get the "insecure" page.

Thanks --

PS: This might be true for other pages at www.gnu.org. I haven't checked.
