Why would System V.4 have the BSD /bin/sh?
The V.4 shell is the V.3.2 shell with job control.
Job control is not enabled by default, only
when the shell is interactive and invoked as "jsh".
Presumably they used this method instead of Korn's -m option
so that you just change your login shell to /bin/jsh.

(This is from the new SVID, I haven't seen V.4 yet).
