and David.  Does it borrow from Linus twice?  Four times?  Does
it stop without falling into endless recursion?  I did not do
this myself because I was lazy and did not want to address these
issues.

I haven't tested these corner cases extensively yet, but from reading
the code it should behave like this:

If you have loops or multiple references to the same repository then
only the first occurance is used.  When reading a reference to an alternate
object store for the second time it is simply ignored.

But of course you should be careful when you set up alternate files.
Having two repositories reference each other and then simultanously
running git-prune in both is obviously not a good idea ;-).

... more testing ...

Well of course practice and reality always differ... I'll send an
updated patch shortly ;-)
