That's comforting to know.

Turns out I was already CCed to bug 596001. So now I've wasted time for all of us. 

But now, at least, any future search for "textarea tabs spaces" will reveal this bug. The bug "All tabs in textareas converted to spaces" could not be located by the same search phrase; somewhat non-fuzzy.
