Doesn't that save the current document when the command is run, rather than running the command when the document is saved, though?

What I'm looking for is a way of hooking the Save command so that the whitespace stripper is run just before saving, regardless of whether I pressed Cmd-S, chose Save from the File menu, or selected Save in the dialog when closing a document with unsaved changes.

I'm sure I read something on a blog which suggested it was possible, but the article unfortunately assumed a greater familiarity with bundle writing than I have :)
