Feature summary (what you would like to be able to do and where):

When a user presses "undo" on an edit of mine and changes things so it's technically not a revert, I want to receive a notification.

Use case(s) (list the steps that you performed to discover that problem, and describe the actual underlying problem which you want to solve. Do not describe only a solution):

Some IP reverted my removal of their unsourced information, this time including a reference to The Sun. Because they added a (useless) reference, it's not technically a revert so I wasn't notified. The links in the edit summary point to Special:Contributions and my talk page, not my user page, so I get no notification from those either.

Benefits (why should this be implemented?):
I could have re-reverted this sooner. And I could have easily missed it altogether.
