I think Emacs does that because the system call invoked by `getcwd' is 
much slower on Unix than an access to the environment variables followed 
by a call to `stat'.  If that is no longer true, we could as well remove 
the `getenv' part and call `getcwd' directly.

However, the case of calling `stat' on directories should be fixed in the 
Windows port anyhow, IMHO, even if it is irrelevant to the issue of PWD.
