[PATCH v2 0/2] rebase -i: a couple of small improvements

Thanks for the feedback on V1. I have decided to split this series so I'm
just posting a re-roll of the first two patches here. The only change is to
reword the commit message of the first patch as suggested by Eric and Dscho

Cover letter for V1: Fix the re-reading of the todo list after an exec or
reword command and stop forking "git checkout" when checking out "onto"

Phillip Wood (2):
  sequencer.c: factor out a function
  rebase: fix todo-list rereading

          This code is heavily indented and obscures the high level logic within
     -    the loop. Lets move it to its own function before modifying it in the

     +    the loop. Let's move it to its own function before modifying it in the
     +    next commit. Note that there is a subtle change in behavior if the
     +    todo list cannot be reread. Previously todo_list->current was
     +    incremented before returning, now it returns immediately.
