Great, I pushed it to git just now! Thanks for testing and confirming.

That's made on purpose. Both nghttp2 and the http2 code in libcurl are still
moving targets and I prefer it to be an active decision to try that out rather
than a wider default check until things stabelizes more. Like a fixed nghttp2
API and a released http2 spec for example.

That's not a bad thought, but is it really feasable? ./configure --help is a
whopping 244 lines already. I count 71 --with* and --enable* lines. The amount
of information there drowns even experienced hackers. I'm far from convinced
that adding 'default' on 70 something places will help...

I consider the final summary output far more helpful actually!
