adds unnecessary complexity and would be IMO not used very much. Please keep the
software simple (I think a warning during preview that someone else has changed
the page is needed by much more people).

This is particularly useful for helping proofread contributed content,
especially when making a few substantive changes to a long article.  This was
the first feature request a friend made, right after I convinced her to start
contributing to WP.

Could always be made a preference (although that adds complexity too), but first
the diff bugs should be fixed so that we can actually _trust_ the diff.

I agree that this would be very useful.  More than half the time I edit I go to
the diff page afterwards to make sure I didn't screw something up.  You can
accidently do a lot without realizing it.  Someone once edited the Capacitor
article and somehow copied the entire article twice into the edit box and saved
it.  So there were two copies of the article in one article, and people started
changing the bottom version and the top version independently without realizing
there were two, which made it difficult to merge the two sections back together.
 Also sometimes people insert special characters without HTML entities which
then get eaten by other browser's text edit boxes, etc.

I would also like to see this implemented, probably as a Preference.  Sometimes 
I'll be editing 5 or 6 articles simultaneously, while looking through an 
additional 5-10 articles/categories for information -- one thing just naturally 
leads to another and another...  Under those circumstances it's often quite 
difficult to remember every change I've made to every article when I finally 
finish my edits.  A "diff-before-submit" feature would be *most* appreciated.
