I had a report that this was broken. It seems fine.

I think the reporter was just never flushing their response
headers.  If I omit the test server's initial Flush I get the
same behavior as reported. (a hang at Client.Get)

Note: This is not a spec change.

The spec was not clear on the result type of
constant shift expressions. Made it more
explicit and added additional examples.

Also: Remove paragraph on send expressions (they
are statements, now).

Fixes #1708.

A FlagSet is an independent set of flags that may be used,
for example, to provide flag processing for subcommands
in a CLI.  The standard, os.Args-derived set of flags is a
global but non-exported FlagSet and the standard functions
are wrappers for methods of that FlagSet.

Allow the programmer to control whether the program
exits if there is a parse error.  For the default set, the behavior
remains to exit on error.

The handling of Usage is odd due to backward compatibility.

A user pointed out that Go didn't work with their
corp proxy, always throwing 400 Bad Request errors.

Looking at the RFC 2616, Host is always required,
even with proxies.

The old code assumed that writing an absolute URL
in the first line of an HTTP request implied
that the Host header was no longer necessary.

Double-checked behavior with curl.

big int support in ASN.1 is a common need and that it should be part

It's documented as such, but it was never wired up
after Transport went in and Head was fixed.

If people don't want redirects, that's what RoundTripper/
Transport are for.  Or a custom redirect policy.
