thanks for checking, yes I expected something like that. I would always suggest checking the output patch from git, it's a good occasion to review your own changes and verify - like in this case - that it's not including unintended or unrelated differences.

WFIW, I think the rebase function included this as you might have had some whitespace changes in some previous patch; I'm not sure of it but that might happen, so you could take this as an example of what happens when reformatting code / whitespace ;-)
