[PATCH 0/3] sane rebase/stash support with submodules

Submodules are special in that they cannot be blindly updated with a checkout. Indeed, submodules do not even have to be checked out (and in that case, must not be updated). It is the user's responsibility to care about the working tree state of submodules.

Therefore, it does not make sense in stash/rebase to test for dirty submodules: they would not be updated anyway.

This patch series does exactly that: working tree states of submodules are ignored with stash and rebase, by calling update-index and the diff programs with the freshly introduced --ignore-submodules option.

Johannes Schindelin (3):
  diff options: Introduce --ignore-submodules
  Teach update-index about --ignore-submodules
  Ignore dirty submodule states during rebase and stash
