Merge branch 'es/rebase-i-count-todo' into maint

"git rebase -i" recently started to include the number of
commits in the insn sheet to be processed, but on a platform
that prepends leading whitespaces to "wc -l" output, the numbers
are shown with extra whitespaces that aren't necessary.

* es/rebase-i-count-todo:
  rebase-interactive: re-word "item count" comment
  rebase-interactive: suppress whitespace preceding item count
