Sure:

  root@usha:/etc# git ls-files -z -o --directory --no-empty-directory 
--exclude-standard --
  root@usha:/etc# echo $?
  0
  root@usha:/etc# touch a
  root@usha:/etc# git ls-files -z -o --directory --no-empty-directory 
--exclude-standard --
  aroot@usha:/etc# echo foo >> inittab 
  root@usha:/etc# # note the heading 'a' before the prompt
  root@usha:/etc# exec git ls-files -z -o --directory --no-empty-directory 
--exclude-standard --
  zack@usha:~$ echo $?
  0
  zack@usha:~$ 

(I'm not sure the last return code is actually faithful, as I haven't
 verified whether su returns to the caller the exit code of the shell
 process.)

Cheers.
