a program being exec'd *must* cause *some* exec commands to be invoked;
...
if it doesn't there's a problem in the kernel, because a program
with no exec commands run will have no address space except the stack,
and i don't think it's valid to have a "run from stack only" exec type,
so panic. if need for that case comes up later, it can be changed...

fixed bug where extra spaces at the end of a shell name would

cause shell scripts to be executed incorrectly. shells would
receive an *empty* arg for name of script, open it, the kernel
would say "oh, that's ." or something similar, and the results
would be interesting... found, diagnosed, and killed by me.
