Hi Alban
This looks good apart from some missing error handling.

edit_todo_list() is changed to work on a todo_list, and to handle the
initial edition of the todo list (ie. making a backup of the todo
list).
It does not check for dropped commits yet, as todo_list_check() does not
take the commits that have already been processed by the rebase (ie. the
todo list is edited in the middle of a rebase session).

If edit_todo_list() fails then the function returns 0. I think you need
to do
if (edit_todo_list() || todo_list_write_file())
return error...
todo_list_write_file() forwards the return value of write_message()
which is 0/-1 so there is no need for the '< 0'

error handling. Also why don't we try parse the file for the initial
edit - is it done somewhere else?
