I thought I saw somebody already pointed out that this was wrong.

I find this somewhat a strange phrasing. It _sets_ the default for
the cover-letter option, either to true or false or auto, so there
is no "in addition" about it.
Perhaps
format.coverLetter::
Setting this variable to `true` (or `false`) tells the
`format-patch` command to pretend the `--cover-letter` (or
`--no-cover-letter`) was given from the command line. When
set to `auto`, `format-patch` assumes `--cover-letter` if
and only if it is working on more than one commit.
or something?
It also is somewhat strange why the command line argument does not
accept `--cover-letter=auto` option. In general, a configuration
variable should not be more flexible mechanism than what the command
line could give the user. As I already said, I think that would be
a better longer-term default, and that makes it even more stand-out.

This part is nicely done, thanks to the previous two steps. You
might even want to remove the call to the find_branch_name() helper
function from here, and instead call it from make_cover_letter()
when branch_name is not yet there.
We would need tests to make sure future changes will not break this.
