Suggested by Jim Meyering.

(_AC_OUTPUT_CONFIG_STATUS): Use it.
Use more quoted here docs to improve readability.
Compute `$me' and use it in the error messages.
Define `$configure' and `$configure_args' to avoid continuously
mixing the uses of `configure' and `config.status' evaluation in a
single line.
Define `$SHELL' and use it.
Simplify all the unjustified `[$]foo' into `$foo', the quotes
are needed only for `$[1]', `$[@]' etc.
Replace all the uses of `ac_cs_root' with files in the tmp dir of
`config.status'.
Remove a few `rm' covered by the removal of the `$tmp' dir.
Let `config.status' support `--debug'.
(_AC_INIT_PREPARE): Avoid the leading space in `ac_configure_args'.
* doc/autoconf.texi (Invoking config.status): Adjust.
Unix 4.0x and 5.0 because `"$@"' expands into an empty parameter
(instead of nothing) when there are no positional parameters.
From Nicolas Joly.

instead of trying to build what `autoheader' needs: let it handle
the format by itself.

The adjustment revealed that `autoconf --trace' is not robust to
single quotes in its argument.
* autoconf.sh: Fix this issue.
Rename the escape `$*' as `$%'. Implement `$@'.
* doc/autoconf.texi: Adjust.
section.
Document --help=short and recursive.
Split the `Directory' section into `Installation directories' for
--prefix and --exec-prefix, and all the others into `Fine tuning
of the installation directories'.
In the latter, don't repeat `in DIR', the user understands, and it
comes out better.
Default for --exec-prefix is PREFIX.
Reported by Kathryn Hargreaves.
Move --host before --build.
Fix a test on `$ac_init_help' which was not updated.

argument of the explicit AC_INIT call is lost.
* acgeneral.m4 (AC_CONFIG_SRCDIR): New macro.
(_AC_INIT_SRCDIR): Adjust.
(_AC_INIT): Pass your argument to AC_CONFIG_SRCDIR.
* libm4.m4 (m4_append, m4_list_append): Use m4_define, not define.
On my machine the former implementation takes 4mn 40s to run the
test suite. Using m4_define leads to 4mn 15s.
* acgeneral.m4 (_AC_SUBST): Use AC_EXPAND_ONCE (which uses
m4_define, not define). 4mn.
(_AC_DIVERT): Don't use m4_case. Starting from those 4mn, if you
just move NORMAL* first in m4_case, the test suite is run in 3mn.
If instead of using m4, you use an `associative array' plus a
wrapper (current implementation), it falls to 2mn.
