Wish: Put full configure command line at the top of config.status

[Niels Möller]

With older versions of autoconf, one could always do

  head config.status

to find out how a package was configured. For example,

  sture $ head config.status
  #! /bin/sh
  # Generated automatically by configure.
  # Run this file to recreate the current configuration.
  # This directory was configured as follows,
  # on host sture.lysator.liu.se:
  #
=># ./configure  --prefix=/sw/local --with-lib-path=/sw/local/lib 
--with-include-path=/sw/local/include --with-scheme=scsh
  #
  # Compiler output produced by configure, useful for debugging
  # configure, is in ./config.log if it exists.

This feature seems to have disappeared in autoconf-2.50. It would be
nice if it was reintroduced, either as a comment near the top of
config.status, or in the output from config.status --help, or both.

Hmm, now I see that the information, with a slightly different format,
is included in the output of ./config.status --version, but I still
think it would be good to have it near the top of the file, The Way It
Used To Be...
