I think I'd prefer to minimize the code under builtin and move this to 
rebase-interactive.c when it is modified earlier in the series. (I'd be 
quite happy if all the files in builtin just consisted of some option 
parsing followed by a call to run_git_foo() which resides in libgit)

Also I wonder if we should be moving more functions (e.g. 
todo_list_write_file() and possibly add_exec_commands(), 
rearrange_squash() and the script generation) from sequencer.c to 
rebase-interactive.c when they're rewritten (possibly in a separate 
commit for ease of review) but I haven't looked if this is practical or 
if there are some dependencies that make that tricky. Unless there are 
some simple cases it should probably be a separate series.

Thanks for working on this series, it's great to see the todo list 
handling becoming more efficient.

Best Wishes

Phillip
