When args.length == 1, then the one element is args[0], not args[1].

args[1] only exists when args.length >= 2.

To expand on that: argv[0] is what is passed to the process the D 
program runs at in the system call it was spawned from (e.g. 
execve), which usually corresponds to the program's name.
