[Qt-interest] License on modified Qt code

[Josh]

Hello all,

As I've mentioned on this list a couple times, I made a modification to 
add line spacing options to Qt. Since I was unable to get my patch 
approved, I've created a separate library (based on Qt code) that adds 
this feature. My question is what text to add to appropriately show how 
the modified file is licensed. I would like to simply re-release the file 
under the same LGPL license.

In order to create my feature I simply modified a single file 
(qtextdocumentlayout.cpp), and created a very simple .pro file which then 
creates a library. I was thinking of simply adding the following text to 
the front of qtextdocumentlayout.cpp. Then I would release my project with 
the qtextdocumentlayout.cpp file (modified), an unmodified 
qtextdocumentlayout_p.h, my new qtextdocumentlayout.pro file, and the 
LICENSE.LGPL and LGPL_EXCEPTION.txt files thrown in with a file called 
notes that explains how to use the feature, how to contact me, and a 
similar statement about licensing to the one below.

Here is the proposed addition to the front of qtextdocumentlayout.cpp, 
please let me know if that sounds about right:
