Shell: Initial support for 'option' completions

Browse source 
Take one small step towards #2357.
Handle completing barewords starting with '-' by piping the requests to
the Shell::complete_option(program_name, option) :^)

Also implements completion for a single builtin (setopt) until we figure out how
to handle #2357.
