When I implemented pushState, I explicitly didn't want authors to have
to rewrite all their anchor links after they changed the document's
current URI.

>From an author's point of view, there's no such thing as the
document's original URI and, unless you're a nerd, you've never heard
of the base URI.  There's just the document's URI, modified by
pushState.

>From this point of view, I'd say it's less surprising that relative
URIs would break when you change directories (hey, you *asked* for it)
than that anchor refs would update the browser's address bar and
document.location relative to the old URI.

If we did make the change you're suggesting, we'd have to check that
it doesn't break at least the major sites which use pushstate
(Facebook, anyone?).  And I'd want to try to coordinate the change
with WebKit so we quickly move away from the old behavior.  But I'm
not convinced it's worthwhile, given that there's at least an argument
for the current behavior.
