* zgrep.in: Don't assume the exit status is the signal number plus
128, as POSIX doesn't require this. No need to kill self; exiting
with large status is enough. Propagate all exit statuses greater
than 1, not merely those in the range 129..143, as there's no need
to treat that range specially (and it's not portable anyway).
