This change retains "or later" state! No licensing _changes_ here,
only form is adjusted (article, space between "GPL" and "v2" and so on).

ed1667e8ee telnetd: add -w ("inetd wait") option. Can be configured off.
gcc fils to fully optimize it out when it's off:

telnetd_main                                        1527    1548     +21
packed_usage                                       26596   26587      -9

but nevertheless it's a useful (and so far single) example
how to write "inetd wait" tcp service.
