[! LSTAT_FOLLOWS_SLASHED_SYMLINK]: Use lstat wrapper.

[Notice the new test in m4/lstat-slash.m4. ]
(main): Back out change from 1999-02-19 that made ls remove
trailing slashes from command line arguments to accommodate early
versions of Linux.  Now, `ls symlink-to-dir/' acts like
`ls symlink-to-dir/.' thus following the symbolic link, as POSIX says
it should.  Suggestion from Bruno Haible and Andreas Schwab.
