You are correct, missed that small difference.

It's also looks like double quote version always are the last one, and is 
the one read by the install tool, therefore the annoying message occurs in 
installations with some history. As I have done upgrades since 3.6.0, and 
first got the error when ugrading to 4.2, it should be easy to "discover" 
when the change is done.

Else I don't think it's necessary to do any compressive check for where and 
when the changes was made. I suppose it's enough to make an either a simple 
check or make a upgrade note.
