+ * FIXME This property is descendant from the original VCS
+ * and used in RCS for user id or "unlocked" strings.
+ * It would be problem to use this under SVN since getting
+ * the locker would need connection to server any time we
+ * load document. SVN currently (mis)uses this as a signal
+ * for locking state, as we do not have API for vcstatus().
+ * The RCS code for user id parsing is working but we don't display
+ * it anywhere. One possibility is to provide proper vcstatus()
+ * interface and kill the whole locker thing.
