HEAD: Bug in simple.el/minibuffer.el causing display-completion-list to delete not only word to be completed but everything in file before it

[Arnold Schwaighofer]

Problem:
In current HEAD display-completion-list deletes not only word to be
completed but everything in file before it.

example:
(defun my-complete-test ()
  (interactive)
  (with-output-to-temp-buffer "*Completions*"
    (display-completion-list
       '("test1" "test2" "test345")
       "test")))

and call that function in a buffer on the word "test" (M-x
my-complete-test) with some text preceeding "test". deletes everything
before word "test" instead of just replacing it.

This also happens when using the complete-tag function :(.

My interpretation of the problem :).

minibuffer.el: display-completion-list
 (set (make-local-variable 'completion-base-size) (or (cdr last) 0))
sets completion-base-size to 0
which causes everything to be deleted before the word to be completed.

the problem
seems to be related to completion-setup-function in simple.el checking
for completion-base-size where i believe it should check for
completion-all-completions-with-base-size
is it possible that it should read:

after applying that patch completion works for me.

bug#591: 23.0.60; lisp-complete-symbol erases extra text

[Drew Adams]

emacs -Q
 
In *scratch*, type this, and leave cursor after the final `for':
 
format-decode-buffer
forward-char
 
for
 
Then hit `M-TAB'. Choose one of the completions using mouse-2 in *Completions*.
 
Only the final `for' should be completed, but instead all of the text
in the buffer is replaced by the chosen completion.

This is a regression from Emacs 22.
