Just a note: “Incorporated Michele Orrù's code style changes into the trunk and other codelines.”

The policy is to apply only bug fixes and doc fixes and improvements to stable branches, not code cleanups (they’re usually compatible but are just not worth doing—at one point code is released and should stop being improved).  This is not worth reverting now, unless the commit was buggy (I didn’t read all messages), I just wanted to restate the policy to avoid such future code cleanups in bugfix branches.  Cheers
