Hi, that worked for me, except I first had to swap the save-excursion
line with the interactive line. Otherwise I get an error message when
trying to call the function. Thanks!

Is this patch something you'll put into geiser master branch, or should
I just patch my own tree? Right now I'm simply defining the new
function from geiser-mode-hook. I suspect it is due to some nuance of
emacs 24 vs 25 and 26.
