Couple of patches

[Pavel Tsekov]

Hello,

I don't like the second hunk of direntry.c.patch.

-       if (write (handle, buffer, n) < 0) {
+       if (write (handle, buffer, n) != n) {
            me->verrno = errno;
            goto error_1;
        }

`errno' is not set if write () returns a positive value i.e.
less bytes written than in the buffer. Also it is ok to have
write () with n = 0 - this should return 0.
