Yeah, but those two are easily recognized, and can be special-cased, if
necessary... Basically, the only issue with those is first canonicalizing
your pathname (a la realpath()), and then names will be the same, no matter
what combinations of "." and ".." you use to reach the real destination...
However, with arbitrarily named hard-links, you don't have the ability to
recognize them... Or, rather, I should say you don't have the ability to
canonicalize them into any single specific format, since there is no "one
true name" for them... Ie: if you have "X" and "Y" as hard-links to the
same exact file, which one is the canonical name?? There's no way to decide
that... But, since everyone knows about the special cases of "." and "..",
those can be handled specially, with little trouble...
