Here's how to automate it.

git format-patch $(git rev-list --max-count=2 <commit-ish> | tail -n 
1)..<commit-ish>

Either way, you need to know <commit-ish>, but this format should be 
fairly easy to add to git-format-patch. If you do, please let the user 
specify the --max-count (but default to 1) so it can be used to extract 
a series of patches rather than just one.
