Merge branch 'js/pull-rebase-i'

"git pull --rebase" has been extended to allow invoking
"rebase -i".

* js/pull-rebase-i:
  completion: add missing branch.*.rebase values
  remote: handle the config setting branch.*.rebase=interactive
  pull: allow interactive rebase with --rebase=interactive

Forward-port from upstream Git.
