Unless running a script (a file beginning with "#!"), Unix sets argv to
exactly what is passed to execve(). If you execute a program with:
char *arg0 = NULL;
execve("foo", &arg0, environ);
the resulting program will have "argc == 0 && argv[0] == NULL".
Setting argv[0] to the name of the program is only a convention, not
something which is enforced by the kernel.
