That's obviously untrue - the shell or the kernel or whatever piece it
is doesn't know what an -E or a -s does, it simply passes them to
python. Now, as the error messages show, it passes them as a single
string rather than (as you would ordinarily expect) as two strings, but
it's all _there_ for python to see, even without trying to read it from
the file (which it also could do).
