Add geiser-mode-eval-to-buffer-transformer
geiser-mode-eval-to-buffer-transformer will take 2 argments: errstring and result when eval-to-buffer, the result will be transformed by this procedure e.g. (setq geiser-mode-eval-to-buffer-transformer (lambda (estring x) (let ((l (length x)) (p (seq-position x ?\n))) (if (and p (< (+ 1 p) l)) (format "\n#| %s%s\n |#" estring x) (format ";;=> %s%s" estring x)))))
