/**
* User script to stash and replay conflicts.
*
* The conflicting edit text is stored under a special title like,
* Conflict:<title>/<base_revision_id>/<conflict_sequence>
* Where the placeholders are, the page title where the conflict occurred, the base revision ID that was being edited,
* and a 1-based sequence which is ignored for now, and lets multiple conflicts share the same base revision.
*
* TODO:
* - Take edit summary from the saved conflict content edit summary?
* - Controls to do advanced things like tweaking the branchpoint and choosing an "other" edit other than
* the target page's latest revision.
* - Proper namespace for these pages.
* - UI labels from messages.
