Setting mid3=mystring+4 points mid3 at memory just past mystring. This
will work for strcat/strcpy so long as mystring is itself allocated,
points to a zero-terminated string and has 4 or more characters (so the
null is at or past mid3). So will strncat and strncpy, since they copy UP
TO 'n' characters, less if they find a null first.
