Accept -- as an "end of options" marker even when using --no-index.
Previously, the -- triggered a "normal" index/tree diff and
subsequently failed because of the unrecognized (in that mode)
--no-index.
Note that the second loop can treat '--' as a normal option, because
the preceding checks ensure it is the third-to-last argument.
