No, just because I patched onto NetBSD 1.4 for testing. When
committing I can upgrade to latest (7.6 I suppose) then apply the
patch.

No, the "colon changed to pipe" patch is not widely used yet.
This will also impact IPv4-only installation, because with "colon
changed to pipe" patch people now needs
to write
telnetd| 127.0.0.1/255.255.255.255
instead of
telnetd: 127.0.0.1/255.255.255.255
and it breaks compatibility with past libwrap (tcp_wrapper)
installations. By using square bracket (my patch) we don't need
to change old configuration files.
I'll try to talk with Wietse beforehand.
