Comment 1 for bug 128562

Specifically, this is related to bug #32669. And relates to our overall decisions as to when to dereference a symlink, and when not to.
In this case, we are dereferencing right away, and so we look at the target of the symlink and start searching for a branch there.
Most likely this is because we are opening a transport using a 'base' of the symlink, which causes us to dereference it. And then when we start walking up from there, we are walking the wrong location.
