[PATCH] submodule status: properly pass options with --recursive

[Jens Lehmann <Jens.Lehmann@web.de>]

When renaming orig_args to orig_flags in 98dbe63d (submodule: only
preserve flags across recursive status/update invocations) the call site
of the recursive cmd_status was forgotten. At that place orig_args is
still passed into the recursion, which is always empty now. This clears
all options when recursing, as that variable is never set.

Fix that by renaming orig_args to orig_flags there too and add a test to
catch that bug.

I noticed that when reviewing Phil's "Teach --recursive to submodule
sync" patch.
