Hello,

When the icomplete-vertical-mode is on, pressing TAB to complete a
single option using find-file C-x C-f behaves as expected but pressing
TAB to select one of two options pops two completions windows and is
unexpected.

To retrace steps,

 1. open "emacs -Q"
 2. M-x icomplete-vertical-mode
 3. navigate with TAB completions after find-file C-x C-f

Say, I want to open the following using find-file C-x C-f

  /usr/src/external/gpl3/gcc/dist/gcc/configure

The directory /usr/src/external has two subdirectories gpl2 and gpl3.

at the point /usr/src/ex TAB completes the path to /usr/src/external/

at the point /usr/src/external/gp TAB completes the path to /usr/src/external/gpl

at the point /usr/src/external/gpl

C-n or C-p will move the highlight between gpl2 or gpl3 (See A)

pressing TAB pops a second *Completions* window (See B)

Expected behavior is for TAB to pick the highlighted directory and continue with path to file selection

There are no 2 *Completions* windows.  Instead, you have one
*Completions* window and the list of completions in the mini-window.

I think this is the intended behavior, and see no bug here.

On reaching the point in the path /usr/src/external/gpl highlighting
either gpl2 or gpl3 in the only 1 *Completions* window and pressing C-j
will enter dired mode for that directory.

Pressing TAB at that point on either highlighted alternatives duplicates
the *Completions* window resulting in 2 *Completions* windows.  And, as
far as I know the user has to mouse select from the duplicated window.

The intended behavior is to get to the target configure file preferably
without needing to mouse point in the second *Completions* window, TAB
would select from the inferred highlighted option.

No, you can select with C-j or with M-TAB.

No, in Icomplete mode TAB does not select.  I suggest to read the
"Icomplete" node in the Emacs user manual, it explains how to use this
mode.

I see, M-TAB is the behavior I intend.  C-j goes to dired mode for the
highlighted directory.

Yes, I should read it.  Thanks.
