This patch improves the readline completion for 'help' to allow
all possibilities including 'help commands' and 'help options',
and at the same time somewhat simplifies the code by making use 
of existing function helparg_accessor().

(The num_args stuff is a bit clumsy and should perhaps just use
sizeof, but this is the same as currently used elsewhere.)
