The correct way to give credit to reviewers is by adding a patch
version changelog, and later including any reviewed-by tags that the
reviewer may give. No need for a sentence like the one above. Just take
a small look at the git log and see how people do the changelogs. Yours
would be something like:
v2: change indentation, add back blank lines (Paulo)
(but I do have to add that the way you changed it was not the way I had
in mind, please see below)

The blank line is usually inserted _after_ the line containing the
closing bracket char. Please see the many examples in the rest of our
code.

I had already complained about indentation before. It's different now,
but it's still not exactly what I was expecting... The idea was indeed
to align the comment indentation with the rest of the "else" case, but
not the way it was done here. Please see the many examples in the rest
of our code.......
