No. What ends up happening is that the sequence of the history list is
preserved, so you can always go back to B. It has the advantage of
reducing bloat, and if one scrolls through history much, that bloat can
be great.

I can see two uses for a history:
1] a log of the sequence in which pages were visited;
2] a list of visited places, in original sequence order.

For me, #2 is far and away more useful.

One problem with the current eww implementation is that once one does
something like A B C D C B, it becomes difficult to get to E using
commands l/r
