OK, this is weird. I think I'm now seeing the same as David on
current master. Note that this is different from what I saw earlier,
when I saw exactly what Eli describes.
0. emacs -Q
1. C-x C-f /tmp/moo.txt RET
2. abc C-x C-s
3. From terminal: echo "foo" >> /tmp/moo.txt
4. type something, get these messages:
moo.txt changed on disk; really edit the buffer? (y, n, r or C-h) y
5. Answer 'y', save the file, get:
- do you really want to save? [not logged]
- moo.txt changed on disk; really edit the buffer? (y, n, r or C-h) y
I tried this several times and got the same result.

File on disk now will become a backup file if you save these changes.

OK, I tried saving a file in my home directory instead, and now I
didn't see the second "changed on disk" message. (That is, I see the
same thing that Eli described.)
Testing it a bit more, I was able to trigger the second message again,
but only once.
---
Investigating even further (on current master), I think I now have
that:
a. In my home directory, I consistently see the message. (David's case)
b. In "/tmp" I consistently do *not* see the message. (Eli's case)
So I guess the second message is triggered only under specific
circumstances?
(But even the above conclusion is confusing, since I also saw the
message (but only once) even when I saved in "/home". And I don't see
why saving in a different directory should matter...)
Does anyone have any idea what could be going on here? Have we found
ourselves a heisenbug? Or have I thoroughly managed to confuse
myself?
Best regards,
