Git Submodule hooks someone else may find of use

A while ago I started a thread discussing my desires to have
submodules automatically update when I switch branches or pull.  This
I desired to occur only if my submodule revision conformed with the
pointer recorded in the superproject's previous HEAD.  In other words,
if my submodule showed as "modified", and I switch branches, I would
desire that this "modified" state persist exactly the same way an
uncommitted change would.

I've created a local git hook to support this behavior.  If it
interests you, you may find it here, under
'git-post-checkout-submodules'.

Installation instructions are found at the top of the script.

Feedback welcome.
