Hello.

I've found some bugs in the function __solve_symlinks:

* It doesn't cope with multiple consecutive slashes. I have a patch for this.

* It doesn't cope with relative paths that use '..' to go above the root
directory. E.g.: c:/tmp/part-symlink/rem_sl is an existing symlink pointing to
a:/loc_reg. Change into c:/tmp/part-symlink, then do:

    ls -l c:../../tmp/part-symlink/rem_sl
    ls -l c:../../../tmp/part-symlink/rem_sl

The first ls command will succeed; the second will fail.

* It doesn't cope with symlinks that point to themselves. For instance:

    ln -s a a

Try to stat the file 'a'. It fails with ELOOP, but it should return
information about the file 'a'.

Bye, Rich =]
