	* acgeneral.m4 (AC_HELP_STRING): Rewrite in m4.  Have m4 work, and
 	give a break to sh.
	(_AC_FOREACH): Be careful not to evaluate the arguments.  A loop
	over *quoted* macro names should loop over the macro names, not
	upon their expansion.
	(_AC_COMMATIZE): Also swallow end of lines.

	* autoconf.texi (Pretty Help Strings): Updated to reflect the
 	changes.

	* acgeneral.m4 (ifset): New helpy tiny macro.
	(AC_OUTPUT): Improved --help of config.status.
	(AC_OUTPUT): Remove inconditionaly all the files to be updated.
	(AC_OUTPUT): Use pid to define the temporary file names in order
	to allow parallel builds.

	* autoconf.sh: Substitute also /@BKL@/[/ /@BKR@/]/ /@DLR@/$/ so
 	that these characters are more easily accessible from m4 without
 	turning changequote juggling into a nightmare.

	* acgeneral.m4 (AC_WRAP): New macro, for word wrapping.

	* autoconf.texi: Update the direntry for more modern Texinfos.
	Add pointer to configure and config.status.
	Remove the dots from the menus: horizontal space is precious.
	(Invoking config.status): More traditional presentation of the options.
