I have two reasons to oppose this patch.

1. If 'len' value is zero, there is an issue already and it should be
taken care of _before_ calling fwrite().

2. xfwrite() doesn't fix anything except for the compiler warning. It
assumes this world is perfect and it's definitely not a place to take
care of the zero-length string.
