This mail didn't reach all intended recipients as there was a newline at
the wrong place in the input for git send-email. I fixed this up for
this reply, please make sure to do the same if you reply to this patch.
The other patches in this thread should be fine. I'm keeping the mail
content below to facilitate replying.
Sorry for the inconvenience,
Uwe
