I don't agree with that comment. I hope you're not suggesting that we look up
all occurences of "!=" and mark them as "yes, we really want this, don't change
it into 'is not'".

But I do think we should make every developer aware that "is not" is different
from "!=".

Ok, then svn annotate the code and write the person who changed it. 
I meant that as it appears to have been changed, it might be changed again. Writing the person directly would indeed be the better thing to do.
