are you sure you want to hard-code to the stable links? seems like not what we
want.

Unfortunately, I've got nothing better than putting "./" in front of it. I think
that should work.  

We can't make the link be different dynamically because it's generated at docgen
time and we don't know then whether useHistory is true or not.  We could do
something in the viewer, but the useHistory version does have anchors, so we
don't know if we see #foo if it's a legitimate anchor or should be converted.
Possibly the other best alternative is in the viewer to try and resolve both
with and without history and see if one of them comes out to be an entity that
exists, but that's trickier.

If this is what we're going to do, can we add a TODO here to load in this page
and resolve the links specified here at dartdoc time, like everywhere else that
we resolve links?
