Hi Wen,

I usually don't take patches that just fix whitespace like this. The
reason is that these sorts of patches tend to make backporting difficult
as they introduce merge conflicts for no good reason.

When you're making substantial changes in an area, then please do go
ahead and fix up whitespace in the same area, but patches that just fix
up whitespace are more trouble than they are worth.

Sorry,
