I'm opposed to overriding /bin/pwd. Csh does not do this. It has a separate  
command "dirs" to give you its idea of the current working directory. Pwd  
should grovel the filesystem and give me accurate (i.e. correct) information.  
Think of pwd as relatively low-level functionality. If you want to introduce  
a higher level user interface, give it a different name.
