[PATCH 2/5] git-submodule: remember to checkout after clone

["Lars Hjemli" <hjemli@gmail.com>]

After the initial clone of a submodule, no files would be checked out in
the submodule directory if the submodule HEAD was equal to the SHA-1
specified in the index of the containing repository. This fixes the problem
by simply ignoring submodule HEAD for a fresh clone.
