Exec'able shell scripts

[Charles LaBrec]

Personally, I like very much the '#!' construction because it allows
you to have set-[gu]id shell scripts.  2.8 BSD even allows you to
have execute-only (i.e., non-readable) scripts.  The 4.x implementation
lets you give flags, e.g. csh -f, so csh scripts can start up reasonably
fast.  True, error messages could be better, but I would protest any
idea to scrap these facilities.
