[Juri Linkov]

branch: emacs-29
commit 7a0eaee198003aa6c1410107f051b45e0b786ce9
Author: Juri Linkov <juri@linkov.net>
Commit: Juri Linkov <juri@linkov.net>

    * lisp/isearch.el: Small fixes.
    
    (isearch-wrap-pause): Mention the new feature of `no' and `no-ding'
    in the docstring.
    (isearch-lax-whitespace, isearch-forward-thing-at-point): Add the
    group 'isearch' since another defgroup changed the default group.
    (isearch-delete-char): Use 'isearch-invisible' instead of 'search-invisible'
    since the users might change the current value with 'M-s i'.
