User:Fnlayson/rollback.js

/* Copied from User:Gracenotes/rollback.js. Thanks!

*

* How to use:

*

* Add the following to Special:Mypage/monobook.js as a

* logged-in user using the monobook skin:

* importScript('User:Gracenotes/rollback.js');

*

* On diff pages, a "summary" link will appear next to "rollback".

* When you click on "summary", you will be prompted to enter a

* summary. Press "Cancel" to cancel, and leave a blank summary

* to use the default. In the summary, the text "$user" will

* automatically be replaced with the user name you're reverting.

* e.g., "rv edits by $user; not true"

*

* "sum" link label changed to "summary" below. -Fnlayson

* update code from User:Gracenotes's page on 1/23/2015.
