Though it's better to set `default-major-mode' and use (goto-char
(point-max)) instead of `end-of-buffer' (which sets the mark) - it
should work as you expect.  But it doesn't.

I tried to edebug `set-auto-mode' - this is where the point is
apparently set to the buffer's beginning.  But the point seems to be
changed magically right after the beginning without any code involved.

Either some hook is doing that, or this is some internal thing at the C
level (bug?).

In a different trial, I traced `goto-char' and `point-min'.  But every
of these calls was inside a `save-excursion'.

So, from the Lisp level, it's a miracle.


Michael.
