I started Emacs with this command:

   ./src/emacs --no-init-file --no-site-file -l ~/tcsh-init.el

The file ~/tcsh-init.el contains the following:

   (setq shell-file-name "tcsh")
   (setenv "SHELL" shell-file-name)
   (setq explicit-shell-file-name shell-file-name)

   (setq comint-completion-recexact t)
   (setq comint-input-ignoredups t)
   (setq comint-input-ring-file-name ".emacs.d/foo_history")
   (setq comint-prompt-regexp "^[a-z]+ [0-9]+ /\\\\ ")
   (setq comint-use-prompt-regexp nil)
   (setq shell-cd-regexp "[cp]d")
   (setq shell-dirtrack-verbose nil)
   (setq shell-pushd-regexp "p(ush|)d")


The first three lines are there to convince shell-mode to start `tcsh'
as the default shell.  The rest are variables customized by original
bug reporter.

My first test was to issue a "pushd /etc" and see if a "C-x C-f" would
offer me that directory as the default one.  Test failed.  Emacs is
not even recognizing "pushd"s.

So I noted that the customization of `shell-pushd-regexp' (see above)
is bogus.  I changed that to

   (setq shell-pushd-regexp "p\\(ush\\|\\)d")

and tried some "pushd"s and "popd"s again.  Emacs seems to correctly
keep track of the working directory now.

The problem was not tcsh specific AFAICT.
