Re: [GSoC][PATCH v3 03/13] editor: add a function to launch the sequence editor

> As part of the rewrite of interactive rebase, the sequencer will need to
> open the sequence editor to allow the user to edit the todo list.
> Instead of duplicating the existing launch_editor() function, this
> refactors it to a new function, launch_specified_editor(), which takes
> the editor as a parameter, in addition to the path, the buffer and the
> environment variables.  launch_sequence_editor() is then added to launch
> the sequence editor.
