With git you need to add all the files, not only the new ones (you can use git
add --update to add the existing files).
Then the patch can be generated (if you don't commit) with git diff --staged

If you commit, you need to add an argument to git diff to tell him a reference
to compare against, namely origin/master (remote master), master (local
master), HEAD^ (last commit before the tip of the branch), etc.  The default
reference if omitted is the tip of the branch, what you have just committed, so
the diff is empty.
