When the user starts an interactive rebase, a todo list is generated, presented to the user (who then edits it using a text editor), read back, and then is checked and processed before the actual rebase takes place. Some of this processing includes adding execs commands, reordering fixup! and squash! commits, and checking if no commits were accidentally dropped by the user. Before I converted the interactive rebase in C, these functions were called by git-rebase--interactive.sh through git-rebase--helper. Since the only way to pass around a large amount of data between a shell script and a C program is to use a file (or any declination of a file), the functions that checked and processed the todo list were directly working on a file, the same file that the user edited. During the conversion, I did not address this issue, which lead to a complete_action() that reads the todo list file, does some computation based on its content, and writes it back to the disk, several times in the same function. As it is not an efficient way to handle a data structure, this patch series refactor the functions that processes the todo list to work on a todo_list structure instead of reading it from the disk. Some commits consists in modifying edit_todo_list() (initially used by --edit-todo) to handle the initial edition of the todo list, to increase code sharing.
