* config/install-sh: Initialize IFS, so field splitting isn't
turned off later.
* config/mkinstalldirs: Likewise.
* config/missing: Remove superfluous quotes. Replace all uses of
`[' by `test', for consistency, and for..
* config/missing (sed_minuso, sed_output): New variables.
(autom4te, help2man, makeinfo): Use them. Unifies detection of
`-o FILE', `--output FILE', `--output=FILE', stricter regex.
Fixes `missing' to detect `--output' for help2man. Fixes
PR automake/483. Report by Dennis J. Linse.
(autom4te): Document in `missing --help'.
* config/install-sh: Don't use 'path' to talk about file names,
as per GNU coding standards. Close a race condition reported by Ralf
Wildenhues and Stepan Kasal. There is still a race condition
on hosts that predate POSIX 1003.1-1992, but we can't help this.
Don't mishandle weird characters like space on pre-POSIX hosts.
Invoke mkdir at most once per dir arg on pre-POSIX hosts.
* doc/autoconf.texi (Programming in M4sh): Cross-reference to
AC_PROG_MKDIR_P from AS_MKDIR_P.
(Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
from mkdir. Mention that Autoconf 2.60 install-sh is safe but
earlier editions are not (including Automake 1.8.3).
Do not suggest mkinstalldirs for thread-safety.
* lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
presence of special characters and race conditions.
* tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
in Autoconf's name space.
* lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
from Automake with minor changes.
* doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
lib/autoconf/specific.m4, lib/autoconf/status.m4,
lib/autoconf/types.m4, lib/autotest/general.m4,
tests/mktests.sh, tests/torture.at: White space cleanup:
remove some SPACE before TAB, or add quoting ('' or @&t@).
so that ac_abs_builddir, ac_abs_top_builddir, ac_abs_srcdir,
and ac_abs_top_srcdir are absolute paths.
* lib/m4sugar/m4sh.m4 (AS_SET_CATFILE): Remove misleading comment.
(&verbose): Remove.
(&getopt): Adjust the note and verb channels, depending upon
--verbose.
* bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
* bin/autoupdate.in: Adjust.
Use &verb, not &verbose.
