I didn't test with -pi.bak so I can't authoritatively say.  

The man page said that -i edited in-place all lines passed through the <>
operator.  I would then surmise that if you don't use the <> operator, it's
not done.  I just haven't tested the theory.  Your version as I recall it
did not seem to actually -take- the input from STDIN or a file, although I
could be misremembering (it's not in front of me).

Easy test is to just drop the whole "if" block you had and replace it with
a single print; at that point.  If you actually get output to your
terminal that matches what you thought you fed it, then you're right.  If
it does nothing, I'm right.
