net/http: clarify client return values in docs · e1d9fcd2

Brad Fitzpatrick authored Jun 19, 2012

Also, fixes one violation found during testing where both
response and error could be non-nil when a CheckRedirect test
failed.  This is arguably a minor API (behavior, not
signature) change, but it wasn't documented either way and was
inconsistent & non-Go like.  Any code depending on the old
behavior was wrong anyway.

I'm not entirely sure why the JSON* numbers have changed, but
eyeballing the profile suggests that it could be spending less
and more time in runtime.{new,old}stack, so it could simply be
stack-split boundary noise.
