--CC _c_o_m_m_a_n_d
_c_o_m_m_a_n_d is executed in a subshell environment, and its
output is used as the possible completions.

The shell function _f_u_n_c_t_i_o_n is executed in the current

--GG _g_l_o_b_p_a_t
The pathname expansion pattern _g_l_o_b_p_a_t is expanded to
generate the possible completions.

The _w_o_r_d_l_i_s_t is split using the characters in the IIFFSS
