There is already logic that determines whether the shell is trying to
complete a command word (in_command_position). The existing code does
not attempt programmable completion if in_command_position == 1. The
additional functionality would:
1. Add an option to the complete builtin to specify how to complete
command names, and store it in a specially-named compspec, like
completion for empty lines does.
2. Add code to invoke that completion, if it exists and programmable
completion is active, before attempting bash's default completion,
if in_command_position == 1.
