["Claus Schneider(Eficode) via GitGitGadget" <gitgitgadget@gmail.com>]

From: "Claus Schneider(Eficode)" <claus.schneider@eficode.com>

- git-add.adoc: Update the --force documentation for submodule behaviour
  to be added even the given configuration ignore=all.

  ignore=all now need --force in order to update the index.
