[PATCH] run-command.c: ensure signaled hook scripts are waited upon

From: Anthony Sottile <asottile@umich.edu>
Date: Feb 21, 2020, 06:06 UTC
Message-ID: <20200221060636.4507-1-asottile@umich.edu>

In the event of a `^C` while hook scripts are running, ensure that the hook processes are cleaned up and do not become zombies. This also ensures that upon `^C` execution is not handed back to the terminal until the processes have been waited upon.
