OT: Using git shallow checkouts

[T o n g <mlist4suntong@yahoo.com>]

Hi,


The git's "shallow checkouts" feature enables people to download the 
latest version of the repository without downloading all the history. 

It is "adequate if you are only interested in the recent history of a 
large project with a long history, and would want to send in fixes as 
patches". http://www.kernel.org/pub/software/scm/git/docs/git-clone.html

But how can I send in fixes?

$ git format-patch origin
fatal: ambiguous argument 'origin': unknown revision or path not in the 
working tree.

please help. 

thanks
