I don't think so. In my OP of this bug I reported the results of `C-x
b' as incorrect (step 8 of the recipe there). In my followup a year
later, I reiterated that the "bug still exists" but added a different
observation of correct behavior involving `C-x b' but incorrect behavior
involving `C-x C-f'. After Stefan Kangas's post revisiting this bug,
which only looked at the `C-x b' behavior of my OP, you implied the
behavior is correct and said you see no bug, to which I replied with
what I intended to be a clarification of my OP, but it seems to have
confused you; my followup to that unfortunately seems to have added to
the confusion concerning the behavior of `C-x b', for which I apologize.
But I hope and think my last reply quoted above is clear: "all the cases
of file name completion differ from the corresponding cases of buffer
name completion. I would prefer buffer name completion to work the way
file name completion uniformly works after your fix." To phrase it in
terms of correctness: the results of `C-x b' in steps 3-4 quoted above
are incorrect; they should be the same as the results of `C-x C-f' in
steps 5-6, which are correct (IMO).
