Re: [RFC] Submodules in GIT

FWIW, here's my view on this issue.

Also, I'd rather expect "git-commit -a" outside of any submodule to
commit everything in the supermodule, triggering submodule commits as an
intermediate step when needed - just like "git-commit -a" does not
require to manually specify subdirectories to inclue in the commit.  I'd
rather expect a special flag to exclude submodules from a commit.

A commit should record the content changes that have been made, not change
any content itself.  Some VCSs change the contents of a file when you
commit them (e.g., keyword substitution).  Git, rightly, doesn't do that.
Likewise, when you commit in the superproject, it should simply record
the changes to the "content" of the subproject and not change it.
And the content of the subproject is a commit, so a commit in the
superproject should not change the content of the subproject by creating
another commit in the subproject.
