The WebKit contribution terms are on the attachment creation page in  

	1) If you are sending in a patch to existing WebKit code, you agree  
by clicking below that your changes are licensed under the existing  
license terms of the file you are modifying (i.e., BSD license or GNU  
Lesser General Public License v.2.1, LGPL v. 2.1). Please also add  
your copyright (name and year) to the relevant files for changes that  
are more than 10 lines of code.
	2) If you are sending in a new file for inclusion in WebKit (no code  
copied from another source), the preferred license is BSD, but LGPL  
2.1 is an option as well. Please include your copyright (name and  
year) and license preference (BSD or LGPL 2.1). By clicking below you  
agree that your file is licensed under either the BSD license or LGPL  
2.1, as indicated in your file.
	3) If you aren't the author of the patch, you agree to include the  
original copyright notices and licensing terms with it, to the extent  
that they exist. If there wasn't a copyright notice or license, please  
make a note of it. Generally we can only take in patches that are BSD-  
or LGPL-licensed in order to maintain license compatibility within the  

Is there something in this case that isn’t covered by those terms?
