Re: [PATCH 1/2] t3507: pin CHERRY_PICK_HEAD absence for a conflicting --no-commit

That doesn't specifically mean that this one test you add here is not

Dropped the test. I went looking for that better argument and did not
find one: t3507 already has 'cherry-pick --no-commit does not set
CHERRY_PICK_HEAD' for the clean pick, and the clean and the conflicting
path go through the same !opts->no_commit guard in do_pick_commit(), so
the regression I described is covered already.

v2 is the documentation change alone.
