ls.c minor diagnostic wording improvement

[Paul Eggert]

ls used quotearg_colon when the context didn't have a colon.  I
installed this fix:

2004-12-16  Paul Eggert  <address@hidden>

        * src/ls.c (print_dir): Use "%s: not listing already-listed
        directory", not "not listing already-listed directory: %s", to
        format already-listed directories, to be consistent with other
        diagnostics involving file names and colons.
