[cfe-dev] -emit-html example

[Nuno Lopes]

Hi,

Thanks for sending a preview! I have been reading the commits in the past 
weeks and I was really curious to see what the output would look like 
(unfortunately I did not have time to play with clang for the last couple of 
weeks).
Anyway, I think the output is great! However I found some little problems, 
like:
 - the output jumps from line 1659 to 2085
 - macro expansion is a bit weird in IE7, at least. the box is very little 
and wraps text after each word (I've attached a snapshot). In Firefox it 
looks much prettier, though.

Keep up the great work!

Nuno
