1a) Teach commit to honor ignore from .git/config.

Why is that problematic after add learned --ignore-submodules=none?

I think the ignore config options and --ignore-submodules parameter
are directly related, as you need the latter to override the former.
In the long run commit should honor ignore=all in .git/config for
unstaged submodules like add should honor the settings from the
.gitmodules file. But we should always add the --ignore-submodules
parameter first so that the user can override the configuration
when needed. So I see these steps:
1) Teach commit the --ignore-submodules option; then make it honor
ignore=all in .git/config in another commit.
2) Teach add --ignore-submodules (which is implied by -f, but only
for the submodules given on the command line); then make it
honor the submodule.<name>.ignore option in another commit.
After that we'd have consistent ignore and override behavior. But
it looks like getting -f right is not easy, so I'd prefer having
1) without 2) if the alternative is to get neither.
