Why does argsdo duplicates a file?

[Igor]

Hi,

on vim 8.1.1244 on Ubuntu I started vim with: vim -u NONE

After using it for a while I decided to open some files into argument list: args *.txt

Now I would like to split those files: argdo vs

What happens is: c.txt is displayed left most, then the same c.txt is displayed in second window,

then b.txt is displayed in its own window and at the right there is d.txt displayed in the last window.

I expected to see c.txt displayed in one single window, but it it displayed in two windows. Why?

Regards

The argdo vs behaves like you'd entered the following sequence:

:vs
:next
:vs
:next
:vs

Each command in isolation is doing its thing correctly.  There's three splits,
resulting in four vim windows.

If what you want is as many vim windows as arguments, in order, try

:1,$-argdo vs | wincmd w
:next

Note there's lots of options affecting vim's behaviour here.  For example, if you have 'splitright' set, it's simpler:

:set spr
:1,$-argdo vs
:next

Even simpler is

:vert all

Thank you John Little for detailed explanation and thanks a lot Gary Johnson for simplified solution.
