getdomainname() isn't guaranteed to null terminate the string if it was 

truncated for length.  SVN 14135 made sure that the truncated version would
always be null terminated.  SVN 14144 broke this for no readily apparent
reason, and I have no idea what it was even trying to accomplish.  Reverted.
