I would much rather see (1). There is a very good reason for
bash-completion doing dynamic loading, which is that loading all of the
completions made shell startup horribly slow. We should do our part to
help keep startup fast by splitting the dynamically-loadable bits from
the must-be-loaded-at-start bits.
