bug#55491: All completion fragments get added to obarray |

Poking at this some more, this behaviour comes from:
(defun elisp-completion-at-point ()
[...]
(fun-sym (condition-case nil
(save-excursion
(up-list -1)
(forward-char 1)
(and (memq (char-syntax (char-after)) '(?w ?_))
(read (current-buffer))))
(error nil))))
That `read' there is interning `ohno' when hitting `C-M-i' after:
(ohno
And that's unnecessary -- we don't actually need the fun-sym; we're just
checking whether we're looking at `ignore-error'. So I've now fixed
this in Emacs 29.
Note that completion in emacs-lisp-mode may still intern stuff, but not
as gratuitously as before.
