This patch was essential to me being able to interact with HTTPS urls in
R.  As far as I understand, by default, R only looks for CURL_CA_BUNDLE
on Windows, but with this patch it looks for CURL_CA_BUNDLE on GNU/Linux
as well.  Is this correct?

I can confirm it works for me, so I'd like to see this patch pushed.

Kind regards,
