When the Geiser minor mode is toggled off using the command
`geiser-mode', the message:
Toggling eldoc-mode off; better pass an explicit argument.
is displayed in the echo area. This is traceable to line 219:
(eldoc-mode geiser-autodoc-mode)
The function `eldoc-mode' takes numeric arguments, while
`geiser-autodoc-mode' returns boolean values. Here is a
simple patch:
(eldoc-mode (if geiser-autodoc-mode 1 -1))
Please find attached a patch file for this change.
