We should work on improving that particular error message to also say what
we can figure out from errno. But in most cases, this is openssl's way of
saying that the connection was unexpectedly closed.

Also interesting: I don't get this problem with the exact same command line
from my machine(s) (I tried from three different ones, using different curl
versions, one test even from this airport wifi).
