        doc            : autoconf.texi 

Log message:
        * doc/autoconf.texi (Special Shell Variables): Mention POSIX
        1003.1-2001's requirements for CDPATH.  Give a simpler workaround
        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        example, since the old example is now out of date.
