A "simpler" recipe (which involves less code) is to go just before "bar"
and do M-: (insert "a") RET

The "simpler" recipe fails in Emacs-23 as well (i.e. the change is due
to the way select+paste changed, rather than to a change in cperl).
It also fails with the "non-Emacs" cperl-mode-5.23 I got from
https://raw.github.com/jrockway/cperl-mode/master/cperl-mode.el, so it
looks like it's not due to our messing things up.

It seems that Emacs lost my bug report. :( Let's try again...

Under X Window (so that Emacs has its own interface), open a file
cperl-font-lock-string starting with:

#!/usr/bin/env perl
# -*- mode: cperl -*-

print <<EOF;
foo
bar
EOF

__END__

with:

  emacs -Q --eval "(progn
    (setq-default mouse-yank-at-point t)
    (custom-set-faces '(font-lock-string-face
                        ((((class color) (background light))
                          (:foreground \"dark blue\")
                        )))))" cperl-font-lock-string

Triple-click on the "foo" line and click with the middle mouse button
to paste. All the lines starting with the second "foo" get colored in
red.

This happens with the Debian package emacs24 24.3+1-1 and this is
a regression in GNU Emacs 24. No problems with Emacs 23.

I've also reported the bug here:

  http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=706701

where you can find a snapshot of what I obtain.
