Describe the enhancement and the motivation for it.
 Code reviewing is great but it is difficult to make comments against the 
 testing box. I find I have to make all other comments first, then hit 
 "Edit Review" button and post them there being very careful to specify 
 to which portion of the test each comment applies. It would be great to 
 have comments tagged to "lines" of the test box similar to how you can 
 do that for lines of code.
 The description box could also benefit from this ability.
 Diffs for those boxes between reviews would also be great.
