No. It doesn't throw out anyhing. It simply doesn't understand them
because there is no shell.
In Unix you can execute a process in two ways: directly by asking the
kernel to start a process based on a certain program, or indirctly by
asking it to start a /bin/ssh image and execute the task as a subprogram
of that. The latter has several advantages (ability to use the shell to
parse arguments and use pipes etc) and disadvantages (security issues,
hidden assumptions).
