   And the like. Someone mentioned an interesting idea where the pwd

   an explicit resync command (tk-resync) instead.

Does csh not have an analogue of bash's PROMPT_COMMAND variable that
gets executed on every prompt?  If so, then it would be trivial to get
that to echo some special code including $PWD and have the shell
filter function watch for that.
