Documentation: full-ness of a bundle is significant for cloning

Not necessarily every bundle file can be cloned from.  Only the ones
that do not need prerequisites can.

When 1d52b02 (Documentation: minor grammatical fixes and rewording
in git-bundle.txt, 2009-03-22) reworded this paragraph, it lost a
critical hint to tell readers why this particular bundle can be
cloned from.  Resurrect it.
