Okay.  I was trying to be exhaustive, even if most of the strategies I
mentioned are insane (“maybe” was probably too strong of a word :)).
(For example, I remember some version of Cygwin requiring the #! line,
so I fear it is dangerous to leave that off.)

After-the-fact s,/bin/sh,$SHELL_THE_USER_WANTS, substitution is the
only sane strategy I have seen used in practice.  POSIX has even
blessed something like it, at last.
