I'm not sure if you can do this with git. However since git is a command
line application it's pretty easy to script it with sh. The negative
part beeing the lack of speed, but since this is a one-time thing I
don't think that it matters.

Since you told us that it is a commit with a huge number of files that
you're looking for, I took that approach instead of calculating the size
of each commit, since that would be more expensive to do.

for commit in $(git log --pretty=oneline | cut -d " " -f 1)
do
	nbr=$(git show --pretty="format:" --name-only $commit | wc -l)
	echo "$nbr: $commit"
done | sort | tail -1

This will give you the commit with most files changed. (Although, there
will be a +1 error on the number of files edited).
