How do I get the terminals in terminal.app to go to the right directory after restart with tcsh?

The terminal.app keeps the tabs after a restart and it even shows the content of the buffers. But all open tabs are at the home directory rather than the working directory they were in at shutdown. I am using tcsh and I learned that this is the problem. It works for bash and Chris Page posted something for zsh , but I do not know how to adapt this to tcsh.
