I'm curious what other people think of this link, I'm not sure it's
right but I can't think of a better behaviour.  In some sense it feels
like blame is a subtype of tree so we should still show the tree link
here, but that makes the "is it active?" check more complicated, and we
can't add blame unconditionally because it has no meaning if the path is
a tree rather than a blob.
