bug#19557: 25.0.50; ido-insert-buffer does not insert virtual buffers.

[Nicolas Richard]

Hello,

When using ido-insert-buffer to insert a virtual buffer (one that is not
live but known to recentf), emacs switches to that buffer instead of
inserting its content into the current buffer.

Here's a recipe:
echo "foo" > foo
HOME=$(mktemp -d) emacs -Q -f recentf-mode --eval '(setq ido-use-virtual-buffers t)' -f ido-mode foo --eval '(kill-buffer)' -f ido-insert-buffer

select "foo" at the prompt (type f o o RET)

Result is : emacs switches to buffer "foo".

Expected was : the file "foo" is opened in a buffer without switching to
it, and its content is inserted in the current buffer.

(I'm going through old bug reports that unfortunately got no response at
the time.)

This bug is still present in Emacs 28.  I haven't tried to debug it
yet -- does anybody else happen to know what's going wrong here?

Actually, I'm not sure there is a bug here.  The case for reproduction
here is from the command line, and the thing that bugs out is that the
command-line setup is trying to switch to the buffer that we already
killed with --eval, and ido doesn't seem to be involved, really.

That is:

./src/emacs -Q -f recentf-mode --eval '(setq ido-use-virtual-buffers t)' -f ido-mode /tmp/foo

and then `C-x k RET' and `M-x ido-insert-buffer RET foo RET' works as
designed.

So I'm closing this bug report.  If I misunderstood what this was all
about, please respond to the debbugs address and we'll reopen.
