Add short a -e alias for --edit to prev and next

I'm not sure if this was an intentional omission, but I think it would be
useful to have `-e` as a short flag for `--edit`. I don't usually edit commits,
but I do use `prev` and `next` with edit to navigate to a commit that I want to
squash. Often this is easier than typing `--from` and `--into` plus the change
IDs.

If people want to edit commits we shouldn't stand in their way.
