patch straight from github!

Wow, this is a cool trick...

1) go to any code on github
2) click on the "commit" link for any changeset
3) add ".diff" to the url
4) now copy the url and voila:

curl [url] | patch -d [dir]

e.g.

curl http://github.com/rails/rails/commit/268c9040d5c3c7ed30f3923eee71a78eeece8a8a.diff | sudo patch -d /Library/Ruby/Gems/1.8/gems/rails-2.3.5/lib/rails


So easy!
