(AC_DIVERT_POP): Move to...
* m4sugar.m4 (_m4_divert, m4_divert, m4_divert_push)
(m4_divert_pop): here.
* acgeneral.m4: Adjust to use only the M4sugar macros.
Nevertheless...
(AC_DIVERT_PUSH, AC_DIVERT_POP): New wrappers around the M4sugar
macros.
(_AC_DIVERT(...)): Rename all the diversions names as...
(_m4_divert(...)): these.
obsolete options to stderr. Adjust list of options. Correct
processing of options. Process options with values separated by
"=" first, so that abbreviations work. Don't accept "=" with
short options.
* autoheader.sh: Likewise.
* autoreconf.sh: Likewise.
* autoupdate.sh: Likewise.
* ifnames.sh: There is no "--verbose" option.
* doc/autoconf.texi: Option "-A" requires an argument.
(autoreconf Invocation): Document "--install", "--symlink",
"--m4dir" and the options passed to Automake.

(AC_SHELL_MKDIR_P, AC_SHELL_DIRNAME): Rename and move to...
* shell.m4 (AS_IFELSE, AS_TMPDIR, AS_UNSET, AS_MKDIR_P)
(AS_DIRNAME): here, a new file.
Adjust all dependencies.

(AC_SHELL_DIRNAME & AC_SHELL_DIRNAME_SED): Eve out into...
* tests/m4sugar.m4 (AS_MKDIR_P, AS_DIRNAME & AS_DIRNAME_SED):
here, new file.
Adjust the test suite.
(AC_STATE_SAVE): ... this. Save the list of all files
in the current directory.
* tests/atspecific.m4 (_AT_CHECK_AC_MACRO): Compare lists of
files created by AC_ENV_SAVE. Remove state* before and after
the test.
(_AC_INIT_PREPARE): Trap after having created config.log.
Also trap on 0.
When trapped, report why in config.log.
(AC_MSG_WARN, AC_MSG_ERROR): Also output the message in
config.log.
(AC_SHELL_DIRNAME): this.
s/X$1/X[]$1/ so that when $1 is a macro, it's given a chance to be
expanded.
(AC_PREFIX_PROGRAM): Use AC_SHELL_DIRNAME.
Quote properly.
ambiguities let's rename `libm4' (M4 code) as `m4sugar':
Readability And Greater Understanding Stands 4 M4sugar

* libm4.m4: Rename as...
* m4sugar.m4: this.
All dependencies adjusted.
`AC_PREREQ'.
* tests/tools.m4: Globally, don't use `../' to invoke the tested
tools, since the PATH is properly set, and in most cases it
obfuscates the test code.
(autoupdating AC_PREREQ): New tests.
are properly templated, autoheader traces
AC_DEFINE/AC_DEFINE_UNQUOTED. Only literals can be traced, and
actually tracing non literals produces invalid autoheader input.
Hence, provide a means to trace calls to
AC_DEFINE/AC_DEFINE_UNQUOTED with literals.
* acgeneral.m4 (AC_DEFINE_TRACE, AC_DEFINE_TRACE_LITERAL): New
macros.
(AC_DEFINE, AC_DEFINE_UNQUOTED): Use AC_DEFINE_TRACE.
* autoheader.sh: Trace AC_DEFINE_TRACE_LITERAL, not
AC_DEFINE/AC_DEFINE_UNQUOTED.
