[PATCH 2/4] Documentation/git-bundle.txt: mention full backup example

[kristofferhaugsbakk@fastmail.com]

From: Kristoffer Haugsbakk <code@khaugsbakk.name>

Tell the user how to make a full backup of the repository right at the
start of the doc.

This is a requested use-case.[1]  But the doc is a bit unassuming
about it:

  “ If you want to match `git clone --mirror`, which would include your
    refs such as `refs/remotes/*`, use `--all`.

The user cannot be expected to formulate “I want a full backup” as “I
want to match `git clone --mirror`” for a bundle file or something.
