Not so quick! You are free to use that in your patches, but please don't
change all code that way without the author's consent. Just like "equals
null" is a natural English way of reading, compared to "null equals
something", "not null" reads like a boolean expression to me, and even
worse while all valid C, "not strcmp" leads to mind-boggling inverted
logic...
