I'd expect, that a null edit does not change the page.
Even in "normal" circumstances this is never a safe assumption.
Let's I save a page [[A]] with {{subst:foobar}} the template for which doesn't exist yet. Then I create the template, possibly to contain something offensive. Then you accidentally vandalize page [[A]] when attempting to do a null (or completely unrelated) edit.
A better question to ask is whether there is some reason to strip white space at one end of the page but preserve it at the other end.
I'm thinking it would be better to strip it all from both ends unless we explicitly use __START__ / __END__ etc.
