git-status does not propagate -uall to submodules

[Thomas Rast <trast@inf.ethz.ch>]

Hi,

While helping with the submodule display on #git I noticed that if you
have a submodule with status.showuntrackedfiles=no, and run 'git status
-uall' from the superproject, then this does not propagate into the
submodule's status.  In code:

  $ (cd bar && git config status.showuntrackedfiles)                  
  no                                                                                                 
  $ git ls-files -s                                                   
  100644 926c01b7259c489a422442a8dc5cb5ea7c58f60c 0       .gitmodules                                
  160000 eb5af46e1a938d064c9f7bae9561013654a43316 0       bar                                        
  $ (cd bar && git status -s -unormal)
  ?? otheruntracked                                                                                  
  ?? untracked
  $ git status
  # On branch master
  nothing to commit (working directory clean)

So far that's expected; after all the submodule is configured not to
display untracked files.  But with -uall:

  $ git status -uall
  # On branch master
  nothing to commit (working directory clean)

Shouldn't the -uall propagate, since the user is explicitly asking for
it?  That is, the display should summarize what git-status *with the
same arguments* would show inside the submodules?
