Yes I know - that wasn't the border to which I was referring.

The only border involved was on a block element - P.bigholder {margin: 0;
padding: 0;
font: 16px/18px sans-serif;
border-bottom: solid 1px green;
color: blue}
SPAN.big {font-size: 160px}

I apologise if I didn't make this clear - the border was not used to check
the border implementation, but rather to test the height of the P.

I've just realised what the problem is. I see what you mean - the
difference is in our respective interpretations of <br>. We were both
working on the same basis - the only difference is with <br>, but I was
going on the basis of:

<blockquote cite="http://www.w3.org/TR/REC-CSS1#br-elements">
4.6    'BR' elements

The current CSS1 properties and values cannot describe the behavior of the
'BR' element. In HTML, the 'BR' element specifies a line break between
words. In effect, the element is replaced by a line break. Future versions
of CSS may handle added and replaced content, but CSS1-based formatters
must treat 'BR' specially. 
</blockquote> 

On the basis that CSS 2 doesn't say anything about BR, I was working on
the basis that it wasn't considered for the purpose of line height
calculations and in particular that:

<line 1>
Some text that reaches a natural break due to it reaching the block edge
</line 1>
<line 2>
And some more text on the next line
</line 2>

In particular, if this had occurred in the case in point; i.e., the break
was natural rather than forced, the height of the element most certainly
would be 54 px.

However, 
<line 1>
Some text that reaches an unnatural end.<br>
</line 1>
<line 2>
And some more text on the next line
</line 2>

Now it seems to be your (and others) belief that the difference is
significant, but in my view it is confusing and unnatural to treat the
<br> as anything other than in the same way as a line break caused through
natural means. I do not see what useful function treating <br> as empty
inline rather than as 'special' serves (particularly in view of the
citation above).
