Subject: tweak "bundle verify" of a complete history

A bundle that records a complete history without prerequiste is a
useful way to sneakernet the sources of your configuration files
under your home directory, etc.  E.g.

    $ GIT_DIR=/srv/git/homesrc.git git bundle create x.bndl HEAD master

Running "git bundle verify" on such a "complete" bundle, however,
gives somewhat a funny output.

    $ git bundle verify x.bndl
    The bundle contains 2 refs
    b2611f37ebc7ed6435a72d77fbc5f8b48a7d7146 HEAD
    b2611f37ebc7ed6435a72d77fbc5f8b48a7d7146 refs/heads/master
    The bundle requires these 0 refs
    x.bndl is okay

Reword "requires these 0 refs" to say "The bundle records a complete
history" instead.
