"git add $ignored_file" fail

Hi *,

      When you try to add ignored files with the git-add command it
fails because the call to:

git-ls-files -z \
        --exclude-from="$GIT_DIR/info/exclude" \
        --others --exclude-per-directory=.gitignore

      does not output this file because it is ignored. I know I can do it with:

git-update-index --add $ignored_file

I understand the behaviour of git-ls-files but I think it is no the expected for git-add, at least for me.

    Thanks

    Santi
