I've found it.

It reads from the register command and ALSO from options IF you tell it
to do so with:

   (void)mod;			/* To stop warning. */
   grub_register_command ("[", grub_cmd_test, GRUB_COMMAND_FLAG_CMDLINE,
			 "[ EXPRESSION ]", "Evaluate an expression", options);
   grub_register_command ("test", grub_cmd_test, GRUB_COMMAND_FLAG_CMDLINE,
			 "test EXPRESSION", "Evaluate an expression", options);
