Bug-Reported-by:        Andrey Zaitsev <address@hidden>

Bug-Description:

Output redirection applied to builtin commands missed I/O errors if
they happened when the file descriptor was closed, rather than on write
(e.g., like with an out-of-space error on a remote NFS file system).

Patch (apply with `patch -p0'):
