Imagine you're on master, then you need to do the following:
# git checkout TYPO3_4-5
# git pull
# git submodule update --init

The "pull" ensures that you get the recent submodule pointers. The
"--init" parameter ensures that the submodules are initialized correctly
if it's the first time on the accordant branch - if initialization is
not required, Git will just do the update - thus "--init" does not hurt.

The difference between svn:externals and the Git submodule is, that in
the Git world a pointer to a specific commit in the submodule is used.
If something is changed in the submodule then the pointer has to be
raised in the super project (TYPO3 Core in this case). Raising the
pointers will be done by the Release Team or any automatic script later on.
