Perhaps the default used for "format-patch" should become different

Good idea.

However, this will require careful research about the best value to use.

An idea would be to use the lore archive to extract patch series
iterations that have been sent to the Git mailing list, then use a
variation of https://github.com/dscho/git/tree/range-diff-from-mbox to
compare them using `range-diff` with multiple creation factors to
determine the bounds within which the optimal value lies.

Sadly a bit too involved a project for me to take on right now.

Ciao,
