Problem is, there aren't always characters available in the right places in
name to be overwritten with zeroes to terminate the various strings.  In unix,
consider the file name "/file".  The directory is "/", the file name is "file",
but there's nowhere to put the zero to terminate the string "/".  A directory
name of "" is not acceptable; it will work under some circumstances (namely,
when a slash and a file name is appended) but not in all.
