[PATCH v4 0/4] More helpful 'git status' during 'rebase -i'

This series makes "git status" provide an output like

  interactive rebase in progress; onto $ONTO
  Last commands done (2 commands done):
     pick $COMMIT2 two_commit
     exec exit 15
  Next commands to do (2 remaining commands):
     pick $COMMIT3 three_commit
     pick $COMMIT4 four_commit
    (use "git rebase --edit-todo" to view and edit)

in addition to the existing output, when ran during an interactive rebase.

Previous version here:

  http://thread.gmane.org/gmane.comp.version-control.git/271184

I just fixed the missing newline I noticed, and squashed Junio's indentation fix. These were the only two remarks on the last iteration.

Guillaume Pagès (4):
  status: factor two rebase-related messages together
  status: differentiate interactive from non-interactive rebases
  status: give more information during rebase -i
  status: add new tests for status during rebase -i
