Fix suppressed blank in completion of `scale --help`

Wrong placement of `compopt -o` introduces an unexpected behavior that did
not matter as long as --help was the only option (you would probably not
continue to type after --help): completion of options would not automatically
append a whitespace character as expected.

For the outstanding addition of the --timeout option, which has an
argument, this would mean that the user would have to type an extra
whitespace after completion of --timeout before the argument could be
added.
