Prevent "scrolling off history"

[ribasushi]

ribasushi> a very small bugreport/wishlist
ribasushi> if one navigates off the history in the irc log browser
ribasushi> ( say via "next day" too many times )
ribasushi> you are sent to a plain No such channel/day page
ribasushi> with no navigation back aside from the browser back button
ribasushi> is it possible to make it work like most webcomics (say xkcd): once you are at the edge, the link loops back to itself?
