Package: emacs24
Version: 24.3+1-1.1
Severity: important

I am not sure if this is one or several bugs, but all these features are
either new or newly turned on by default and they all seem to be related
to a single feature, so I believe there is just one bug somewhere.
Steps to reproduce: start emacs, visit a file, switch to another program
and change the file you just visited (touch will do, but it really has 
to be a different program, running M-x shell or similar won't do).

Nothing happens, just as supposed. Now switch back to emacs and it pops
up an annoying dialog window about an altered file it is visiting almost
immediately.

Here is the first bug: *almost* immediately: if you are quick, you can
alter the buffer before the window steals focus. Suppose you were not 
that fast, so the buffer is unaltered, and you answer "no" to the dialog.

Here is the second bug: emacs shows another, identical, dialog. If you
keep answering "no", emacs shows 3-15 identical dialogs, asking the very
same question. (It's possible it only shows 3 if you were not fast enough,
I got too angry to test more, but it's quite possible the number of dialogs
equals 3+number of changes you made before the dialog appeared.)

Close emacs. Start is again, visit the file again, but this time alter the
buffer before switching away and touching the file in a terminal (or
whatever you like to do to make emacs think it has been altered) and then
go back to emacs again. Answer "no" to the dialog as many times as emacs
asks you and then save the buffer. Emacs now asks you the usual question
about a file changed on disk, to which you should answer to save the 
buffer anyway.

Here is the third bug: now emacs asks you whether you want to revert the
buffer or overwrite the changed file with your buffer, but then immediately
(you might be fast enough to answer that first, please be slow) asks the
new question about discaring edits because the file your buffer is visiting
has changed.

At this point, emacs is unusable: the first question has apparently removed
all keybindings since there is no way of making the second question go away.
Any key I press causes the same message to be displayed: "<key> is undefined".

I cannot save the file, revert the buffer, or even C-g or Esc, because every
key I can think of is undefined. Likewise mouse. (Menu works, but does not
help.)

Expected outcome:

Bug 1: nothing. No questions, no dialogs, nothing. Or at least an option to
turn this annoying new feature off.

Bug 2: Just one question per buffer.

Bug 3: Buffer saved according to my wish.

Cheers,
Juha
