No, I did not miss the reference to the 1988 vintage sh test. That's much too late, I cannot even imagine what might have been done to that shell (that was probably a SysVR3 shell, which had lots of changes). The one I am referring to was the original 7th edition (and 32V) shell from Bell Labs. In that, there was no --, to set the args, "set a b c" would fail if "a" happened to start with a '-' (it would be interpreted as option flags). The workaround was "set - a b c" but that would reset all the flags (there was no "set +..." in that shell, the when a '-' option was given to "set" it cleared the flags, and then set those given.) Hence, "set -$- a b c" - set the flags back to what they were, and then set the positional parameters. I used this long before ash was needed (which was between 4.3BSD and 4.4 at the time of the lawsuit - sometime early/mid 90's). Get yourself an original 4.2BSD /bin/sh and test that one - Berkeley did almost nothing to sh (everyone used csh) so that should be quite close to the v7 version.
