I think the discussion here is a bit tangential to the original topic.
The point you make is reasonable, but it seems a bit more likely that in
the case Peter cites the symlink is one level higher in the tree, in
which case there's probably little value in resolving the symlink. Maybe
we could compromise and check if a path exists and only resolve symlinks
if it does not?
