It looks a bit extensive since that prompt just requires
path to init(8) by default and those keywords are exceptions,
unlike the bootloader prompt.

How abouht this way?

- if input strings are started with "/", try to exec it
- if input strings are not startd with "/" check option keywords
- if none matches show
use absolute path, ddb, halt, or reboot
  like root device prompt:

>> root device (default wd0a): help
>> use one of: tlp0 wd0[a-p] ddb halt reboot
>> root device (default wd0a): foo
>> use one of: tlp0 wd0[a-p] ddb halt reboot
>> root device (default wd0a):
