AFAICT, M-p already brings in the previous value of the variable, if it
was set:
(let* ((var (read-envvar-name "Set environment variable: " nil))
(value (getenv var)))
(when value
(add-to-history 'setenv-history value))
;; Here finally we specify the args to give call setenv with.
(list var
(read-from-minibuffer (format "Set %s to value: " var)
nil nil nil 'setenv-history
value)
t))))
> If the variable was initially set outside of Emacs, it won't be in history.
Do you have a recipe to reproduce this?
What is the value of (getenv "FOO") before you run `M-x setenv'?
