[PATCH 11/15] rebase-interactive: append_todo_help() changes

[Alban Gruin <alban.gruin@xxxxxxxxx>]

This moves the writing of the comment "Rebase $shortrevisions onto
$shortonto ($command_count commands)" from complete_action() to
append_todo_help().

shortrevisions, shortonto, and command_count are passed as parameters to
append_todo_help().

During the initial edit of the todo list, shortrevisions and shortonto
are not NULL.  Therefore, if shortrevisions or shortonto is NULL, then
edit_todo would be true, otherwise it would be false.  Thus, edit_todo
is removed from the parameters of append_todo_help().

edit_todo_list() and complete_action() are modified to fit these
changes.
