[PATCH] Show number of commits being rebased interactively

[Onno Kortmann <onno@gmx.net>]

During 'rebase -i', a wrong edit command might inadvertently drop
commits. This change shows the total number of commits in the comments below
the commit list. After a rebase edit, this number can be quickly compared to
the line number of the last commit in the rebase TODO list.
