Tarring up ports tree somemore

[Ian McWilliam <ian_(_at_)_dodo_(_dot_)_com_(_dot_)_au>]

Actually as a follow on

MAXPATHLEN PATHMAX has been changed over the years to 1024 characters.

name_split from tar.c defines

        if (len > (TPFSZ + TNMSZ))
                return(NULL);

TPFSZ is 155, TNMZ is 100 characters (255 characters). Has the standed 
for the ustar header been changed at all over the years? if so maybe we 
need to fix tar?
