I guess that in the future commit the return value of get_todo_path()
would change depending on what sequencer is used for, cherry-pick or
interactive rebase, that is, contents of replay_opts...

...and that's why you have added this temporary variable here, to
not repeat get_todo_path(opts) calculations...

... So that's why it is s/git_path_todo_file()/todo_file/ replacement,
and not simply...

...the s/git_path_todo_file()/git_todo_path(opts)/, isn't it?

Looks good; though I have not checked if all calling sites were converted.
