I tried today. Before this change no arguments got passed down and
afterwards they are (but just the arguments, no submodule paths
were passed on in either case; which is what Kevin fixed in the
commit Heiko referenced). Three arguments are allowed for "git
It doesn't matter if we pass that on or not because $recursive is
reused when "eval cmd_status" is executed.
Same as recursive, GIT_QUIET is set the first time and then reused
in the recursion.
This was dropped when recursing into submodules but isn't anymore
with Heiko's change, so we do have a change in behavior here.

Hmm, when --cached is used together with --recursive, I would expect
it to show the commit stored in the index for the deeper submodules
too (and not magically switch to show their HEAD again after the
first level of submodules). To me this looks like a bug which Kevin
accidentally introduced and nobody noticed and/or reported until now.
So I'd vote for making this a bugfix patch for "git submodule status
--cached --recursive" (and would love to see a test for it ;-).
