If people want to go that way that is fine by me, but unlike the ones that
are _ejected_ from next without trace, if we are going to have the primary
feature the patch introduces and changing only a minor detail of external
interface, I don't think we gain much by hinding that story from the
history, especially for something that has been cooking in 'next'.

A separate follow-up commit would be more honest about the feature's
history.  Also a follow-up patch to remove conditionals is much easier to
review than a resend of a rewritten patch, especially when the original
was reviewed adequately for its primary codepath to implement the feature.

Would it be just a matter of queueing something like this on top of
b8ac923 (Add an option for using any HTTP authentication scheme, not only
basic, 2009-11-27)?

Subject: Remove http.authAny

Back when the feature to use different HTTP authentication methods was
originally written, it needed an extra HTTP request for everything when
the feature was in effect, because we didn't reuse curl sessions.

However, b8ac923 (Add an option for using any HTTP authentication scheme,
not only basic, 2009-11-27) builds on top of an updated codebase that does
reuse curl sessions; there is no need to manually avoid the extra overhead
by making this configurable anymore.
