Hi Alban

Thanks for working on this. I've got a couple of specific comments 
below. On a more general level I'd be tempted to squash the two patches 
together rather than adding the tests as a separate commit. Also I think 
before we discussed having `rebase --continue` refuse to continue if 
`rebase --edit-todo` had dropped commits when rebase.missingCommitsCheck 
was set to error. I think that would be useful but could always come 
later. --edit-todo could write a file to .git/rebase-merge to prevent 
--continue from continuing in case of errors.

Do we want to print this advice when `rebase --edit-todo` detects 
dropped commits as well? I'm not clear what error messages are printed 
it that case. If we always want this printed then it could be moved into 
edit_todo_list()

Thanks again for working on this, it's a really useful addition to rebase

Best Wishes

Phillip
