[PATCH] pull: respect submodule update configuration

[Stefan Beller <sbeller@google.com>]

From: Lars Schneider <larsxschneider@gmail.com>

Do not override the submodule configuration in the call to update
the submodules, but give a weaker default.

Personally I dislike this patch, but I have no better idea for the time
being.

Thanks,
Stefan
