Well, it was, unless you were a vi user.

But the bug was never part of a released version, and the patch isn't 
exactly backporting material.  So it doesn't really matter from a 
release documentation and tracking perspective.

I can file a bug and put it into the appropriate state.  I normally file 
such bugs only if there's a risk I get side-tracked and fail to fix the bug.

Thanks,
Florian
