This rewrites append_todo_help() from shell to C. It also incorporates some parts of initiate_action() and complete_action() that also write help texts to the todo file. This also introduces the source file rebase-interactive.c. This file will contain functions necessary for interactive rebase that are too specific for the sequencer, and is part of libgit.a. Two flags are added to rebase--helper.c: one to call append_todo_help() (`--append-todo-help`), and another one to tell append_todo_help() to write the help text suited for the edit-todo mode (`--write-edit-todo`). Finally, append_todo_help() is removed from git-rebase--interactive.sh to use `rebase--helper --append-todo-help` instead. Signed-off-by: Alban Gruin <alban.gruin@gmail.com> --- The changes are due to the rebase, no real changes otherwise.
