bug#22003: 24.5; *vc-dir* show ignored files for Mercurial

[Oleksandr Gavenko]

In GNU Emacs 24.5.1 (x86_64-pc-linux-gnu, GTK+ Version 3.18.2)
 of 2015-10-24 on trouble, modified by Debian
Windowing system distributor `The X.Org Foundation', version 11.0.11702000
System Description:     Debian GNU/Linux testing (stretch)


>From some newer version of Emacs (I currently on 24.5.1) after some operation
`*vc-dir*` buffer begin to show *ignored* files.

I specially craft `.hgignore` to make list of `hg status` short. But Emacs
`vc-mode` doesn't respect my preference.

Is it possible to ignore *ignored* files? I kill *vc-dir* and reopen in order
to hide *ignored* files.

To reproduce:

 * open `*vc-dir*`
 * modify file
 * undo changes on file from `*vc-dir*`
 * refresh `*vc-dir*` content

I made wrapper to diagnose problem:

    #!/bin/sh
    echo hg "$@" >> ~/tmp/hg.log
    /usr/bin/hg "$@"

>From above instruction steps I got log:

    root       # here I press C-x v d
    id -b
    id -t
    status -C ./   # below I edit and save file
    hg --config alias.status=status --config defaults.status= status -A hg.rst
    hg --config alias.status=status --config defaults.status= status -A hg.rst
    hg parent --template {rev} hg.rst
    hg --config alias.status=status --config defaults.status= status -A hg.rst
    hg --config alias.status=status --config defaults.status= status -A hg.rst
    hg diff hg.rst       # <== revert file in *vc-dir* by C-x v u
    hg revert hg.rst
    hg --config alias.status=status --config defaults.status= status -A hg.rst
    hg root            # <== here I press g
    hg id -b
    hg id -t
    hg status -C ./
    hg status -mardui -C hg.rst ./

Last command include `-i` option which cause issue. Sources have:

    $ grep -R -n mardu
    lisp/vc/vc-hg.el:640:         (concat "-mardu" (if files "i"))

which is:

    (defun vc-hg-dir-status-files (dir files update-function)
      (apply 'vc-hg-command (current-buffer) 'async dir "status"
             (concat "-mardu" (if files "i"))
             "-C" files)
      (vc-run-delayed
        (vc-hg-after-dir-status update-function)))

`lisp/vc/vc.el` state that:

    ;; - dir-status-files (dir files update-function)
    ;;   If FILES is non-nil, this function should report on all requested
    ;;   files, including up-to-date or ignored files.
