The current best practice involves these steps:
1. Create a topic branch (git checkout -b feature-name)
2. Apply your changes and commit them, preferrably in small and isolated 
steps, making sure it compiles after each change.
3. Run "git format-patch origin".

This will result in one or more commit-patches, which contains your 
author info, the commit-messages you wrote, the commit-time and all 
other such info and ofcourse the diff in unified git format. You can 
send those patches on using "git send-email" or apply them using "git am 
-k 00*.txt".
