The commented line is indented with spaces whereas everything else is using
tabs. Python doesn't like this to be mixed.

I am not a fan of formatting strings like this, because I find it hard to read,
and this doesn't work when one of the variables isn't a string.

Why does this patch remove the proxy for HTTP without mentioning it? I know that
we only send requests via HTTPS now, but I think generally this should be
configured just in case.
