Re: [PATCH] submodule: add --no-fetch parameter to update command

git submodule update --no-fetch makes it possible to use git submodule
update in complete offline mode by not fetching new revisions.

This does make sense in the following setup:

* There is an unstable and a stable branch in the super/master

repository.

* The submodules might be at different revisions in the branches.
* You are at some place without internet connection ;)

With this patch it is now possible to change branches and update
the submodules to be at the recorded revision without online access.

How is this better than "cd submodule/path && git checkout whatever"?

It is better if you have a complex setup recorded in the master repository.

If my co-worker commited his newest revisions for the "stable" branch, I
might not know which of his revisions I need to checkout.

Another advantage is that with -N the update operation is faster,
because fetch is checking for new updates even if there was no
fetch/pull on the super/master repository since the last update.

Do we know this is common enough to deserve a shortopt -N?

I don't think so, gonna resend later.

The logic of the patch itself looks sane to me.

Nice.

Best Wishes,
