I eventually solved this with:
(defun grass (full-location)
"Call grass with FULL-LOCATION arguments and set up a shell buffer
to work on. FULL-LOCATION must be a fully-qualified GRASS location;
i.e. it must include GISDBASE/LOCATION_NAME/MAPSET.
The GRASS process runs in a shell buffer, named *GRASS*."
(interactive "DLocation: ")
(let ((grassbuf "*GRASS*"))
(shell grassbuf)
(comint-send-string grassbuf (concat "grass " full-location "\n"))
(setq comint-input-ring-file-name
(or (getenv "HISTFILE")
(concat (directory-file-name full-location)
"/.bash_history")))
(comint-read-input-ring)))
Cc'ing the grass-user list where it might be of interest.
Thanks,
