So today the topic of trailing whitespace came up. Git complains about trailing whitespace, but only in the diff: wouldn’t it be great to see this in your editor?

I did some Googling search around, and found remy sharp’s b:log: Trailing white space in TextMate. I uses a similar technique to my Adding #pragma mark to EVERY LANGUAGE you work with (in TextMate): create a source bundle, include it in the languages you use, etc.

After you apply the bundle update you need to switch your current window’s language to something that doesn’t inherit from source, then switch back and try it.
