[PATCH 5/5] mv: be quiet about overwriting

When a user asks us to force a mv and overwrite the
destination, we print a warning. However, since a typical
use would be:

  $ git mv one two
  fatal: destination exists, source=one, destination=two
  $ git mv -f one two
  warning: destination exists (will overwrite), source=one, destination=two

this warning is just noise. We already know we're
overwriting; that's why we gave -f!

This patch silences the warning unless "--verbose" is given.

You could perhaps argue that it is useful in the case of moving multiple
files into a directory (since it tells you _which_ files were
overwritten). We could turn the warning on in that case, but I'm
inclined to leave it. If the user cares about this information, they can
use "-v" along with "-f".
