/**
The main function. Does nothing but return the number of arguments.
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.
