bug#4699: 23.1.50; lisp-complete-symbol erases text

[Markus Rost]

Recipe:  Prepare buffer *scratch* as follows

=== Buffer *scratch* =======================================
;; This buffer is for notes you don't want to save, and for Lisp evaluation.
;; If you want to create a file, visit that file with C-x C-f,
;; then enter the text in that file's own buffer.

(symbol
============================================================

Put point after "(symbol", hit M-TAB (or M-x lisp-complete-symbol) and
in buffer *Completions*  click with mouse-2 on "symbolp".  The buffer
looks now as follows:

=== Buffer *scratch* =======================================
symbolp
============================================================

The problem does not depend on the particular buffer (same problem in
Emacs-Lisp mode buffers) and the particular word to be completed.

The problem does not appear with lisp.el.~1.103~, the version before
the following change:

	* emacs-lisp/lisp.el (lisp-complete-symbol): Use minibuffer-complete.

I've installed a set of changes which I believe will finally eliminate
all these kinds of bugs (mostly by replacing completion-base-size by
a new completion-base-position variable).

Lucky me:  I have never met it in person.

Wow, looks like you have changed the bigger part of Emacs.

The original problem is fixed for me.

As a matter of fact you have, as is witnessed by your bug-report.
You just didn't know its name.

I just have too much time, too little to do.
