If we use the typographical rules then, actually, we don't have to 
(re)define it :)
By that I mean that if you ask 10 typographic experts and the fast 
majority will come up with the same answer we don't need to write that 
answer down. It is up to the implementer to gather that information.

With my typographical background, I'd say;
If you consider one line of characters a block, from top of font to bottom 
(with the baseline in between) and the linespacing being excluded from 
this block, then the overline would IMO be at the top of that block.
If it grows thicker it then eats away at the linespacing (50%) and at the 
tops of the ascenders (50%).
