It follows from the POSIX Pathname Resolution spec (4.11):

"A pathname that contains at least one non-slash character and that ends 
with one or more trailing slashes shall be resolved as if a single dot 
character ( '.' ) were appended to the pathname."

IIRC, Windows operates the same way

Not sure I understand your point. Could you clarify with an example?

Hard links have been supported for quite a while. Symlink creation work 
is stalled because of other commitments. May be ready for the next 
release, at least for files. For directory support on Windows, there are 
some really tricky issues that have bogged work down.
