/***
*char *strncat(front, back, count) - append count chars of back onto front
*
*Purpose:
*	Appends at most count characters of the string back onto the
*	end of front, and ALWAYS terminates with a null character.
*	If count is greater than the length of back, the length of back
*	is used instead.  (Unlike strncpy, this routine does not pad out
*	to count characters).
*
*Entry:
*	char *front - string to append onto
*	char *back - string to append
*	unsigned count - count of max characters to append
*
*Exit:
*	returns a pointer to string appended onto (front).
*
*Uses:

*Exceptions:
