fddbd11baa made it so the command executed
read `sh -c -- '"script" args*'`, the -- in this command is redundant as
the script name never starts with a dash and can never be interpreted as
an option or a flag.
The actually meaningful placement for -- here is after `$SUDO`, to make
sure `$SUDO` does not incorrectly treat `-c` as an option to itself, and
`$SHELL` cannot be interpreted as an option/flag in the extremely
unlikely event that it starts with a dash.
