If you type an unrecognized command, you get an "Error: unrecognized
command X" error, then a list of similar commands, followed by a
recommendation to check out 'doom help Y' or 'doom --help Y', where Y is
the nearest recognized parent command. E.g. 'doom ci blah' is an unknown
command, but 'doom ci' is known, therefore Y = 'doom ci'.
This fix ensures that Y is properly resolved.
