Never say that. ;-)

Sorry, I can't reproduce that.

My guess is that it might be a problem with vanilla `savehist.el' as well,
because I don't think I changed any of the code concerning that. Or it might
be a problem with Emacs 21's treatment of `compile-history' - that is, it
might be completely unrelated to savehist.

La petite histoire : `savehist-20+.el' is only a trivially modified
`savehist.el': it just doesn't rely upon features that older Emacs versions
don't have. Emacs developers didn't want to make the trivial changes that
would let `savehist.el' play well with other versions - they don't care
about that. So I posted `savehist-20+.el' at Emacs Wiki.

Perhaps someone else can reproduce the problem you see? Either using
`savehist-20+.el' or `savehist.el' (with Emacs 22 or later).

Try testing with a .emacs that contains only (require 'save-hist-20+). And
perhap try starting over by deleting your file `savehist-file' (default:

I think you're saying that this is what you see:

1. Open Emacs, then `M-x compile RET foobar'.
2. Close and reopen Emacs.
3. `M-x compile RET <up>' shows message "no preceding item".
4. <down> shows ? (what does it show?)
5. <up> shows `foobar'.

Is that right? I don't see that. At step 3, I see `foobar'.

After step 2, visit `savehist-file'. What do you see recorded for
`compile-history'? You should see something like (setq compile-history
