I first thought that unsetting *check_todo in do_pick_commit(), when
!is_rebase_i(), was a clean solution.  But sadly it is *not* a godo
equivalent to Gábor's patch, because check_todo can be set to true
without looking at is_rebase_i() in pick_commits() [*1*].  To ignore
that setting where the variable's value is used, the hunk we see
above in the beginning of this message is necessary.

That was what I meant.  I think the "This is what I had before"
patch matches my "I first thought" version, so we were on the same
page and both wrong ;-)

Thanks.


[Footnote]

*1* I still do not know why a47ba3c7 ("rebase -i: check for updated
todo after squash and reword", 2019-08-19) sets check_todo to true
without looking at is_rebase_i().  If this unconditonal setting in
TODO_EXEC did not exist, I think your "This is what I had before"
patch would have been equivalent to Gábor's patch.
