As an aside: any reason you use /bin/pwd instead of the shell builtin pwd?
The problem seems to be that `sh_canonpath' is called to set the
working directory (`set_working_directory'), but the value of PWD is
not updated with the canonical version.
Here's what I think is the fix. I'm not sure if the set_auto_export is
needed, most likely it isn't.
