As said in the reply to Junio, this patch has been sitting on my hard drive
for a while and was written before you started the attempt to de-globalize
the state of git.

Ideally this setting would be part of the repository object. For example
the repository object would have a "submodule_config" pointer, initialized
to NULL, which can then be set to the read config or a static empty_config
if no such config exists.
