"now" meaning which version of quilt?  I still see this on 0.48 if that
matters.

Yes, quoting is the correct thing to do, but that does not usually
happen in "Signed-off-by:" lines in kernel patches.

Actually, I think this is even a problem when the name is quoted
properly, I've had to fix that up in patches by hand.

And yes, this is a problem, I run into at least 1-2 patches per stable
kernel release with this issue.  I looked into fixing it and somehow the
email parsing logic was wierd and I couldn't figure out how to resolve
it.
