Comment on "Recipes" - previous page link

[VictorNicollet]

In http://guide.couchdb.org/draft/recipes.html you explain a simple pagination system using startkey. However, you don't really explain how the "previous" link is going to work. The only explanation you provide is this:

Populating the link to the previous page is as simple as carrying the current startkey over to the next page. If there’s no previous startkey, we are on the first page.

This works when moving from page 4 to page 5 (just remember the link to page 4), but it cannot work when moving from page 5 to page 4 (there's no way for page 5 to know that what the startkey of page 3 should be). So, I suspect there's another detail here that you did not mention.
