Yes, I guess that's probably the right decision.  But you cannot use
AS_EXECUTABLE_P in _AS_DETECT_BETTER_SHELL: the shell detection has to
be done before (because the `test' used may change).

This currently leads to a configure script that hangs; you can try this
with regenerating Autoconf's configure, and running
  ksh ./configure

Cheers,
Ralf
