In my first example above, I'm editing the 2nd commit and it applied
cleanly. What I see in that case is
pick 4th commit
pick 3rd commit
2nd commit <-- YOU ARE HERE
1st commit
2nd commit is the current HEAD, which corresponds to the last entry in
the "done" file, so there's no reason to display the "done" file entry
too in this case.
Only if it wasn't applied cleanly (and wasn't rescheduled) do I want to
show the "done" entry. This way I always see four entries in my list, no
matter what happened (unless I drop commits, of course), which is what I
want.

That would also be possible, but in lazygit it makes things harder,
because items from "git-rebase-todo" can be interacted with (e.g. moved
up or down, or dropped), whereas the "done" entry is only for display
purposes and can't be interacted with. That's why I called it a "fake"
entry above.
I tried the algorithm now and seems to do exactly what I want, so thanks
for the help with this, I'm happy now.
There's a slight correction though: if a command is rescheduled, then
git appears to re-append the last successful command to the end of the
"done" file (it's in there twice now). So I have to check the
second-to-last command of "done" against the first command of
"git-rebase-todo" to find out if a command was rescheduled.
