If I understand it correctly this is a problem only in Ubuntu
currently. They bumped libcurl3 to libcurl4 but only for the openssl
flavor of libcurl, supposedly because they added support for nghttp2
in this build. I don't think they realized this would create a split
in the ecosystem between software that depends on libcurl3 vs

I *think* that if you are building debian r-base against
libcurl4-openssl-dev, then it will automatically start depending on
libcurl4 once this makes it into testing:

Either way you know this better than me. I was mostly giving users
like myself a heads-up that when they try to upgrade to ubuntu 18.04,
apt may uninstall r-base or other packages trying to resolve the
libcurl3 vs libcurl4 conflicts.
