which had trailing whitespaces.

Uhm, yes. Why do you ask? ;) 
I forgot again that it is too late to edit the patch when send-email asks:
> Send this email? ([y]es|[n]o|[q]uit|[a]ll): 
as it has read the patch from disk and keeps it in memory I assume?

I just wrote the commit message as I would do, but offer you to claim authorship
for that perl stuff. So in case you'd want to reword that, I'd ask you to that.
Also asking for your signoff. (But apart from that I consider this patch final.)

Thanks,
Stefan
