That's fine. Stupid of them, but OK.
According to our code history, that's the way it came from AT&T in 1988.
It looks like they added it in SVR4.0 - I don't see it in the SVR3 sources
we have archived.
They used it in the implementation of the killall command (to translate the
signal argument) and of the /bin/sh shell (for the kill builtin, and as
guessed, for trap).
