/**
* Display list of a post's revisions.

*
* Second argument controls parameters:
* (bool) parent : include the parent (the "Current Revision") in the list.
* (string) format : 'list' or 'form-table'. 'list' outputs UL, 'form-table'
* outputs TABLE with UI.
* (int) right : what revision is currently being viewed - used in
* form-table format.
* (int) left : what revision is currently being diffed against right -
* used in form-table format.
