Why this? As a result of this change, it's forcing my editor (bbedit) to trim trailing whitespaces in a file every time I save.  That makes for a lot of unrelated changes on every patch.  Is this really necessary?

Yeah, I think we should remove this line from .editorconfig.
I'm working around this issue by adding

let g:EditorConfig_disable_rules = ['trim_trailing_whitespace']

to my .vimrc :P
