I took this to mean "absolutely we need --no-full-diff." :)

I note that --full-diff sets rev->diff = 1. The log.fulldiff config
option does not, and nor does --no-full-diff unset it. However, I'm not
sure it makes sense to set it. Doing "git-log --full-diff" outputs an
extra line (separating the diff from the commit log) but since we
haven't told it any type of diff to output, the diff is blank. And if we
had told it a type, then that would have turned on rev->diff. So I don't
see a point in setting it.
