As it appears this particular change has agreement from several
people, I created a PR that hopefully implements it:
https://github.com/WebKit/WebKit/pull/13441. This does not touch
.editorconfig as I'm pretty sure that always ends up applying to the
entire modified file.

I would like to thank everyone for their input and at the same time
apologize for the whitespace removal in my earlier set of patches.
