// This script implements a very crude one-click undo. If you go onto a diff page with an undo link, this will change it to work in one single click rather than two.
// It also adds a "revert" link to edits on contribution pages, that works the same way (one click).
// Known glitch: Does not work as intended if a user has edited the same page multiple times (to avoid this, I recommend ticking the "Only show edits that are latest revisions" box.
