Minor niggle: you don't really need to say what version the patch is 
against in the commit message, as the version will have changed by the 
time the patch is committed.  It can be mentioned after the "---" marker 
line if relevant, as the stuff after the "---" line does not end up in 
the commit message.

The patch itself looks fine!
