Hmmm...I'm not really sure about Linux and it's been several years since
I thought about this on any Unix, but I thought that the problem with
the shebang lines wasn't number of arguments, but number of bytes (but I
thought the limit was longer than you're using there). Also, I don't think
it gets interpreted by your shell, but by the underlying system call that
tries to execute the file.  But I haven't looked at the source code in
the system that would be doing all that work, so I don't really

Sorry I don't have any real answers...
