bug#10873: 24.0.93; `report-emacs-bug' obscures bug-reporting buffer (!)

I meant that when the window gets removed or reused there's no guarantee
that processing the completions will succeed.

Or not to reuse it for showing another buffer.  That's what the
dedicated flag seems to be for.

That's the idea, I think.

I said that Emacs is nice.  It lets the user remove or reuse the window
and thus terminate the completions dialogue.

That this completions dialogue cannot be continued reliably.

I don't remember ever having contributed anything to the completions
code or to ‘report-emacs-bug’ so I cannot be more concrete.  I meanwhile
pushed the change proposed earlier.  If you don't like the new behavior
you will have to come up with a suitable solution.  Eli said that we
must solve this bug.
