Provides functionality to show a diff between two node revisions.

Code

function diff_menu() {
  $items = array();

  /**
   * By using MENU_LOCAL_TASK (and 'tab_parent') we can get the various revision-views to
   * show the View|Edit|Revision-tabs of the node on top, and have the Revisions-tab open.
   * To avoid creating/showing any extra tabs or sub-tabs (tasks below top level) for the
   * various paths (i.e. "Diff", "Show latest" and "Show a specific revision") that need
   * a revision-id (vid) parameter, we make sure to set 'tab_parent' a bit odd.
   * This solution may not be the prettiest one, but by avoiding having two _LOCAL_TASKs
   * sharing a parent that can be accessed by its full path, it seems to work as desired.
   * Breadcrumbs work decently, at least the node link is among the crumbs. For some reason
   * any breadcrumbs "before/above" the node is only seen at 'node/%node/revisions/%/view'.
