Merge branch 'js/rebase-i-dedup-call-to-rerere'

"git rebase -i", after it fails to auto-resolve the conflict, had an unnecessary call to "git rerere" from its very early days, which was spotted recently; the call has been removed. * js/rebase-i-dedup-call-to-rerere: rebase -i: remove an unnecessary 'rerere' invocation
