;; FIXME da: this one function breaks the nice configuration of Proof General:
;; would like to have proof-goal-regexp instead.
;; Unfortunately Coq allows "Definition" and friends to perhaps have a goal, 
;; so it appears more difficult than just a proof-goal-regexp setting.
;; Future improvement may simply to be allow a function value for
;; proof-goal-regexp.

;; FIXME Pierre: the right way IMHO here would be to set a span
;; property 'goalcommand when coq prompt says it (if the name of
;; current proof has changed).

;; for the french:
