* man execve *

Well, well. I knew that some unices had to be doing this because they
allowed suid scripts. But I thought the behaviour had been phased out
of newer versions. (Because Linux and the like don't allow suid
scripts, I assumed that this whole script-handling behaviour had been
moved out of the kernel.)

I learn something new every day. Thanks. :-)
