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)))))
