bug#11117: Suggestion to mark the the arrow for translation

[Göran Uddeborg]

When printing a symbolic link in ls, the target of the link is printed
like this:

      if (f->linkname)
        {
          DIRED_FPUTS_LITERAL (" -> ", stdout);
          print_name_with_quoting (f, true, NULL, (p - buf) + w + 4);

I would suggest marking the arrow for translation.

          DIRED_FPUTS_LITERAL (_(" -> "), stdout);

In translations using Unicode a "real" arrow, the "rightwards arrow"
(U+2192), can be used instead of the "ascii art arrow" traditionally
used.
