Sorry for the late reply!
Okay, here is what I get with a fresh .emacs that contains only
(require 'save-hist-20+), also I delete any old .emacs.d/history file.
1. open emacs, `M-x compile RET' (shows 'Compile command: make -k'),
remove 'make -k' and type 'foobar' RET.
2. close and reopen emacs
3. M-x <up> (shows 'compile') RET (shows 'Compile command: make -k')
4. <up> (shows 'Beginning of buffer. No preceding item' and jumps back
to 'Compile command: make -k')
5. <down> (shows 'Compile command:')
6. <up> (shows 'Compile command: foobar')
If on 6., I type <down> again, instead of <up>, I get 'End of history:
No default available', then <up> shows 'Compile command: foobar'
The fact that the fresh emacs shows 'make -k' as a default is kind of
unexpected, right? May this pre-setting be the cause of the trouble?
Note that on step 1., I did not press RET for make -k, and still it
shows up again after restarting emacs.

What is 'savehist-file'? If you want me to do M-x savehist-file --
that's not available. Or did you mean something else? (sorry, although
I'm a heavy emacs user, I'm not an expert in the jargon! ;-)
