Actually including a 1990/1993 UCB copyright is -exactly- why 
the from: line should be there.  If he had assigned his own
copyright to this I wouldn't of batted an eye, but he didn't,
which means he copied it from someplace.  I would like to have
that someplace clearly documented as has always historically
been done when copying parts of or whole files around the
BSD source tree.

His commit message also lacked any details about this move
of code, it just said, build with WARNS=6.

They do if they infact copied a portion of another file...
