[PATCH 11/17] get: don't try to parse --unknown as -- -u -n ...

[Rob Browning]

Unrecognized arguments that start with a double dash were being
treated like composite single dash arguments like -xyz because the
check for the second dash was broken by py3, i.e. by str[i] being an
integer now, rather than b'x'.

The effect was confusing, but not a risk because the resulting
synthetic "--" argument was also unrecognized.
