let git-ls-files suppress the expanding of all files in sub directory

["lilinchao@xxxxxxxxxx" <lilinchao@xxxxxxxxxx>]

As subject said, is this possible for git-ls-files to work like this?:
" $ git ls-files --no-recursion
    a.txt
    b.txt
    dir/
"
instead of:
" $ git ls-files 
    a.txt
    b.txt
    dir/one/two/1.txt
    dir/one/two/2.txt
    dir/one/3.txt
    dir/4.txt
"

Does it make sense?
