+ This command, unlike all other fish commands, does not feature a -h
+ or --help option. This is because we want to avoid errors on arrays
+ that have -h or --help as entries, which is very common when
+ parsing options, etc. For this reason, the main fish binary does a
+ check and prints help usage if -h or --help is explicitly given to
+ the command, but not if it is the contents of a variable.
