The current page will always be the current page,
regardless of archive sorting order. Page 76 of
86 pages will remain page 76, even if the archive
sorting is changed; it won't become page 10.
Fixes#625 in core.
Themes will have to cope with the sorting order
in their pagination code if they want to display
a descending order for stable archive sorting.
