Merge branch 'rs/show-progress-in-dumb-http-fetch'

"git fetch" over HTTP walker protocol did not show any progress
output.  We inherently do not know how much work remains, but still
we can show something not to bore users.

* rs/show-progress-in-dumb-http-fetch:
  remote-curl: show progress for fetches over dumb HTTP
