I agree that there is not much reason to push mark when point does not
move.

I slightly disagree about the case of opening new file.  I personally
find it useful when the first element added to mark ring is BOB.  When
cycling across mark ring, BOB is a nice visual indication that I already
looked across the whole ring, especially if I am searching for mark that
is actually not in the mark ring (though I thought otherwise).

On the other hand, it is rather a matter of personal preference.  Not
pushing BOB to mark ring might be a better default.  Even if it not, we
would probably need to change other places across the code to add BOB
consistently.  That's a whole other discussion.

See the updated patch.  Hopefully I got the news entry for Emacs 29.1
right.

Best,
Ihor
