Great, thanks.

I'm sorry if I confused you here, but I should have typed *merge*,
which means the merge buffer (with *emphasis* on the word merge).
This buffer is named "file-prefix", because of the way I invoked
Ediff.

Yes, of course.

As I said, the merge buffer is called "file-prefix", and there is
only one of these buffers.

Yes, note that now I am running emacs21.
I just ran a simple test case and this problem still exists.
Note that I *invoke* ediff like this:
(ediff-merge-files-with-ancestor file-a file-b file-c nil file-prefix)
or like this,
(ediff-merge-files file-a file-b nil file-prefix)
in the simple test that I just ran, I used the former.

It appears that "file-prefix" must not exist before invoking
Ediff.
Also, please try to run your test case by invoking Ediff from
the "*scratch*" buffer, which is in Lisp Interaction mode. You
may have to run the test case twice before "#file-prefix#" is
created and then left hanging around after the merge has completed.

ps - this is my test case,
$ head f_*
==> f_A <==
this is f_A
==> f_B <==
this is now f_B
==> f_C <==
this is f_C common ancestor
(ediff-merge-files-with-ancestor f_A f_B f_C nil f)
then I used these commands to ediff: n
b
