One problem is that if a subsystem has a lot of failures (perhaps even
just trailing whitespace in comments?), then the flag will be off for a
long time (forever?) and we won't catch new problems.

I think a git hook is the right place to do it but a buggy git hook is
worse than no git hook.
I know we're trying to keep the emotion out, but I still don't
understand what's wrong with using highlighting in an editor. Another
thing is that "git show" (or log, or whatever) highlights trailing
whitespace... so provided the submitter looks at the changes using a
tool like this then they will see the trailing whitespace.
peace & happiness,
