Dear "Reinhard Meyer (-VC)",

NAK.

Please submit as one patch so we have an atomic, bisectable commit. Thanks.

Best regards,

If A equals success, then the formula is A = X + Y + Z. X is work.  Y
is play. Z is keep your mouth shut.                 - Albert Einstein

Dear "Reinhard Meyer (-VC)",

But please clean up the code berfore resubmitting...

...

No trailing white space - please fix globally

Long lines wrapped by mailer. Please fix your mailer setup (or rather use "git send-email" for sending patches.

Note: line too long - please fix globally.
