Updates showmediuminfo command

Starting from 7.x version of VirtualBox, vboxmanage command help gives
its usage with one or more lines per command, like:

  VBoxManage command <args> [--option1|--option2] [--option3=optarg ]

There is no need to get it as in old format from now on.

+VBoxManage bash completion script
+=================================
+
+This version of the completion was initially based on Sebastian T. Hafner
+script. However, in some point of time I've decided to rewrite it almost from
+scratch.
+
+Current version of script was written and tested against VBoxManage in version
+6.1.38, and should contain all commands and their options.
+
+Unlike other attempts, I've tried to make the script context aware. See the
+simple session with the VBoxManage command below, to have an idea how it works:
+
+.. image:: /images/vboxmanage_session.gif?raw=true
+   :alt: VBoxManage session
+
+
+Note, that ``startvm`` command proposes only VMs, which are not running, while
+``controlvm`` will complete only running VMs.
+
+What is worth to mention, this completion script is a real thing, so it only
+offer things which have sense for particular commands, for example:
+
+.. image:: /images/vboxmanage_snapshot.gif?raw=true
+   :alt: Take a snapshot
+
+For ``snapshot take`` subcommand, the only options which are proposed are
+``--live`` and ``--description``. Other commands and subcommands are behaving in
+similar way.
+
+
+Installation
+============
+
+Either source the file::
+
+    $ . /path/to/this/repo/VBoxManage
+
+or add it to a proper place depending on your distribution. Usual place would
+be:
+
+* ~/bash-completion.d/
+* /usr/local/etc/bash-completion.d/
+* /etc/bash_completion.d/
+* etc.
+
+It's also okay to copy it into some directory, and place proper line in
+``.profile`` or ``.bashrc``::
+
+    source /some/directory/VBoxManage
