Make navigating small and/or whitespace changes easier

A common problem we have is stray small edits in Outline

Sometimes you're on an Outline page and you accidently hit a \r\n or a \s while on the page and not realize it.

All of those subscribed to the page for updates receive a "Page Blah Blab updated" with a blank looking update (see screen shot below)

And then when one goes to visit the page and try to find where the stray space was made, the change history/diff view doesn't make it obvious where the change is.

There's a couple of ways to improve this (#1 is the most complete solution IMHO)
1) Provide a feature (automatic, or a button/link) that allows pointers to all the changed lines to be highlighted in a meaningful way (perhaps at the right or left side bar of the line that was changed?)
2) Provide an option not to receive updates that are whitespace only
3) ???
