The real curl code clearly didn't use shutdown, and worked correctly
with all the servers, so I dropped broken-http-proxy when I did the
curl-shim.  Unfortunately, I missed that the code defaults to use
shutdown.

I can see how this might have been necessary with old HKP servers in
the past, but they don't really exist any longer.  There certainly are
no original PKS servers left at this point.  The few (one?) that are
left are running the fixed PKS I made to not eat subkeys.  That PKS
also properly handles HTTP/1.0 requests with the blank line.

I think the right fix here is to either hardwire HTTP_FLAG_NO_SHUTDOWN
to on in curl-shim, or just remove the shutdown stuff altogether.
