Re: [PATCH 09/16] entry.c: optionally checkout submodules

We may need an option to ignore these failures. Maybe even active by
default. Imagine a superproject with _optional_ submodules, where it
is just nice to know that some submodules weren't checked out. BTW,
doesn't git-checkout already prints an error?
