`CURL_CA_BUNDLE` is *only* used if we can't already find certs in their "standard"-ish locations. It is the fallback added purely for my co-workers on Macs, who don't have an easily accessible cert list available. I had never heard of it being set session-wide until the topic of exporting certs from Keychain came up over lunch one day.

I should have kept quiet, this isn't helping either of us get stuff done :P
