That depends wholly upon the shell. C-shell variants do it one way, sh
sorta does it like zsh (the items marked with a `*' above are like csh,
but because sh doesn't appear to have a builtin cd(1) or pwd(1)). Zsh
does it (by default?) the same way that ksh does.
The use of symlinks pointing to subdirs has long been flagged as A Bad
Idea due to the handling of `..', so "ymmv" when you choose to use them.

And ksh does the same thing. Again, sh(1) doesn't do this because it
doesn't have a builtin pwd(1).
I'm surely not complaining about how zsh handles either of these behaviors,
I prefer a ksh-on-steriods look and smell for a shell.
