From: Phillip Wood <[email protected]> While a rebase is stopped for the user to edit a commit message it can be convenient for them to also edit the todo list. The scripted version of rebase supported this but the C version does not. We already check to see if the todo list has been updated by an exec command so extend this to rewords and squashes. It only costs a single stat call to do this so it should not affect the speed of the rebase (especially as it has just stopped for the user to edit a message)
Note that for squashes the editor may be opened on a different pick to the squash itself as we edit the message at the end of a chain fixups and squashes.
