Subject: 23.1; M-x C-p C-p ... showing strange history elements
Date: Mon, 14 Dec 2009 15:19:04 -0500

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the bug-gnu-emacs <at> gnu.org mailing list,
and to the gnu.emacs.bug news group.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:


M-x C-p C-p ... shows strange entries, even with -Q, e.g.

quail-show-keyboard-layout
makefile-makepp-mode
plain-tex-mode
shell-dynamic-complete-command
update-autoloads-from-directories
php-mode
...

If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file
/usr/share/emacs/23.1/etc/DEBUG for instructions.

Do you mean you see unsorted commands while typing `M-x M-n M-n ...'?

   Do you mean you see unsorted commands while typing `M-x M-n M-n ...'?

I meant that I never ran those commands, so they shouldn't show up in
the minibuffer history, yet they do.

They don't show up in the minibuffer history when you type
`M-x M-p M-p ...'.

M-x M-n M-n ... shows random entries that were never called by the
user; even when using -Q and first thing after start up when the
mini-buffer history is supposed to be empty.  That is a bug, or
undocumented feature.

Sorry if I was unclear.

I agree that pushing completions to M-n of M-x is confusing.
I don't find this feature useful.

Then set minibuffer-default-add-function to nil.

I think `minibuffer-default-add-completions' as the value of
`minibuffer-default-add-function' is useful for a list of buffers
for buffer-reading commands because there are ordered by recency.

For most other commands, completions are unordered, so perhaps we should
set `minibuffer-default-add-function' to `minibuffer-default-add-completions'
only for buffer-reading commands.

Yes, I agree.  But I'm not sure if this should be done for the next release,
because currently there is feature freeze.  Or this counts as a bug?

   Then set minibuffer-default-add-function to nil.

Can we set this as the default? The current behaviour is not
intuitive, or useful.
