In general, we don't usually take patches that just clean up whitespace
damage or stylistic problems. Doing so makes backporting harder as you
end up having to pull in extra patches to fix up minor differences
before bringing in substantive patches.

If you're fixing a real bug in the same area, then sure, go ahead and
fix up the style in the surrounding code, but if these patches don't
fix real bugs then I'd suggest not taking them.
