Git problemos with the JSCocoa submodule

[Gus Mueller]

When doing a fresh checkout of JSTalk, and then updating the submodule-
some funkyness is happening:

$ git submodule init && git submodule update
Initialized empty Git repository in /private/tmp/jstalk/jscocoa/.git/
remote: Counting objects: 3471, done.

Unable to checkout '963fdc753ee58badf14701f61b594d7d8e2b9fff' in
submodule path 'jscocoa

I think I might have screwed something up when possibly playing with
JSCocoa files…
(see: http://www.mail-archive.com/bug-co...@gnu.org/msg16418.html
and http://stackoverflow.com/questions/2155887/git-submodule-head ).

At any rate- does anyone know how to fix this the proper way, or maybe
know what it is I did to cause this, and how to keep it from happening
in the future?
