* ReverseChronologicalPager is a child class of the abstract IndexPager, and

+ * parameters, in addition to any subclass-specific parameters.
* * The offset is the non-inclusive start of the DB query. A row with an
* index value equal to the offset will never be shown.
* * The query may either be done backwards, where the rows are returned by
* user, or forwards. This is specified by the "dir" parameter, dir=prev
* means backwards, anything else means forwards. The offset value
* specifies the start of the database result set, which may be either
- * the start or end of the displayed data set. This allows "previous"
+ * the start or end of the displayed data set. This allows "previous"
* links to be implemented without knowledge of the index value at the
- * start of the previous page.
+ * start of the previous page.
* * An additional row beyond the user-specified limit is always requested.
* This allows us to tell whether we should display a "next" link in the
* case of forwards mode, or a "previous" link in the case of backwards
* mode. Determining whether to display the other link (the one for the
* page before the start of the database result set) can be done
- * heuristically by examining the offset.
