`--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
keep `--prefix foo --prefix bar' as `--prefix foo bar'.

configure.ac variables (such as VERSION etc.), but also on prefix
and so forth, depend on Makefile, not configure.ac.

around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
For LC_ALL etc, first try to set to "C" as POSIX requires and as
the Autoconf documentation specifies; fall back to "unset" only if
this fails. Use a shell for-loop for this rather than an m4 loop,
to shorten the output script.

for the CDPATH problem. Document PWD.
(Limitations of Builtins): Document the problem that "cd $foo" and
"ls $foo" may refer to different directories in shells conforming
to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
example, since the old example is now out of date.
* lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
FOO" and "ls FOO" talk about different directories; this catches
problems when POSIX 1003.1-2001 "cd" fails due to symlink
spaghetti.
* lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
of rolling our own unset.
