I recently moved from GNU Emacs 23.3.1 to GNU Emacs 24.0.91.1 (both on
debian). Mostly I'm happy, but a change in behavior of isearch is
annoying me, and I'd appreciate help fixing it in my configuration.
Consider the following (cited) fragment of a log buffer:
> ----------------------------------------------------------------------
> M 10 Oct 11:
>
> build 08:35-12:07
> run 13:45-16:15
> debug 17:00-17:39
> doc, commit 18:50-19:39
>
> ----------------------------------------------------------------------
> T 11 Oct 11:
Put point at the beginning of the (uncited) fragment (i.e., remove the
citing, and put cursor atop the first '-'). In emacs 23 (and for as
long as I can remember before that), if I then did
C-s C-y C-s
I would get a search for the entire first line (of '-'): point would be
at the end of the second separator, which would be found/highlighted--
this I expect, know (certainly my fingers know this :-), and prefer.
But in emacs 24,
C-s C-y C-s
causes a (usually failing) search for whatever was last killed; instead,
to get the desired behavior, I must do
C-s M-s C-e C-s
Is there an easy way to make my init.el (aka .emacs) tell emacs 24
that I want the old semantics for this usecase? Alternatively, how
best/easiest to restore the old behavior?
TIA, Tom Roche <Tom_Roche@pobox.com>

(define-key isearch-mode-map (kbd "C-y") 'isearch-yank-line)
How to find that out easily on your own? Look in the isearch.el code. Or ask
Emacs itself, like this:
1. Load this library:
http://www.emacswiki.org/emacs/download/help-fns%2b.el
2. C-h M-k isearch-mode-map
Do that in Emacs 23, and you see that `C-y' is bound to `isearch-yank-line'.
Do it in Emacs 24, and you see that `C-y' is bound to `isearch-yank-kill' (and
`isearch-yank-line' is bound to `M-s C-e', as you noticed).

Right, but then I need to find that. Much more conveniently:

Yes indeed! help-fns+.el works as advertised, just
0 Download help-fns+.el to a directory in your load-path.
1 I byte-compile-file'd it in emacs 23, per emacs-version
interoperability instructions in file.
2 Add
(load "help-fns+")
to your init.el or helper file.
3 Restart emacs.
thanks, Tom Roche <Tom_Roche@pobox.com>

That ought to be documented in NEWS (C-h n).

Did you install 24 from a debian pkg or build from sources yourself?
If from debian pkg, what did you need in /etc/apt/sources.list to find
a pkg for emacs-24?
