Ah, no it doesn't.

C-x h M-x untabify RET

Dang.

BTW, for the Emacsen in the audience, here's a little elisp I use to normalize whitespace. I mostly use this in Python code so YMMV. It frst untabifies the buffer, and then it deletes bogus trailing whitespace. I think it mostly works. ;) The defalias is just because I can never remember what I called the function and don't have it bound to a keychord.
