O.K.

-D option may be insane, or simply don't work correctly because we used
to move files in repository in the past.

How about "-r HEAD"?

I get unexpected files when I do

  % cvs co -P -r HEAD basesrc/usr.sbin/sendmail

Isn't "-r HEAD" useless, too? or Is repository wrong?

(If someone fix these files state, please check entire source...)
