2. New Specification

Though I do not remember why to have made it to such a specification,
maybe it was to avoid parsing a file many times.
Anyway, I think it is bad specification or a bug.
Maybe you don't want to follow links that go out of the source tree (eg.
/usr/include or whatever), but then you have to check every path component
(boring but possible).
But worse, symlinks can create loops:
$ ln -s .. foo
