A stop: or reload: script written with a timeout killed Finit at
config load:
service stop:5,/bin/true service.sh -- Boom
parse_script() takes the timeout as a pointer and the caller decides
whether it wants one. However, both stop: and reload: scripts so far
have no timeout, i.e., NULL. Guard the branch that reads a leading
number.
