Sorry, I'd misunderstood your original message. So the problem is that
you want "git submodule status" to be quiet (i.e. not print an error
message) when it dies of SIGPIPE?

I assume git is dying with SIGPIPE. As the only purpose of "git
submodule status" is to write the status information to stdout that
sounds reasonable. If you want to collect the exit status you need to
consume the whole output so that the command runs to completion.
