Hmm.  Well, there are a number of ways that a shell could calculate that a
file is executable.  One of them is to use the access(2)/eaccess(2), which
asks the kernel to calculate the current process's effective rights for a
file.  To figure out where things are going wrong, you could try a few
things.  First off, try using the access(1) command to test for execute
rights on the target script.  If that works right, we should take a look
at the shell's implementation of tab completion.

Hmm.  It sounds like the archive provided by securityfocus isn't currently
working.  I'll look into setting up one on the TrustedBSD web page
directly.

That is not a problem from my perspective, as you seem quite willing to
help figure out what went wrong :-).
