I realized that defining the glissando gradient taking the stencil as point of 
departure, rather than the grob properties, makes it work for broken glissandi 
too. It was a quite minimal change. 

(gliss-gradient (/ (+ (- (car stil-y-ext) (cdr stil-y-ext)) (* half-line-thick 
                                (+ (- (car stil-x-ext) (cdr stil-x-ext)) (* 
half-line-thick 2)) 
                                (if (> Y-right Y-left) 1 -1)))
