;; Show where vile looks for keyword file, and where it finds it. If we
;; always implemented built-in filters, the natural place for this would be
;; within filters/filters.c - and no need for a macro. But we may have
;; configured with external filters. Rather than maintain two chunks of
;; similar C code, this is implemented as a macro (as an exercise ;-).
