I took a look at this, and indeed, it breaks existing code. But the
broken code is wrong and is easy to fix. So here is a series to do this,
on top of the one I am responding to.

These ones shouldn't have any functional impact, but do clean up the
code. I'd recommend the regression fix I already posted for maint and
1.8.0, and leave these to cook for post-1.8.0.

  [1/2]: remote-curl: do not call run_slot repeatedly
  [2/2]: http: do not set up curl auth after a 401
