I haven't seen such an option, but I think it would be nice to be able to ignore submodules when creating a stash. When I stash changes in a directory, almost always I intend to only stash real files, not modified submodules. When I pop the stash later, it gets disrupted due to submodule conflicts. To avoid getting the conflicts in the first place, it would be nice to somehow specify:
$ git stash push --no-submodules -- MyDirectory/ Would this make sense?
