It has been reported than running
git submodule status --recurse | grep -q ^+
results in an unexpected error message
fatal: failed to recurse into submodule $submodule
When "git submodule--helper" recurses into a submodule it creates a
child process. If that process fails then the error message above is
displayed by the parent. In the case above the child is killed by
SIGPIPE as "grep -q" exits as soon as it sees the first match. Fix this
by propagating SIGPIPE so that it is visible to the process running
git. We could propagate other signals but I'm not sure there is much
value in doing that. In the common case of the user pressing Ctrl-C or
Ctrl-\ then SIGINT or SIGQUIT will be sent to the foreground process
group and so the parent process will receive the same signal as the
child.
