To tell whether Ken installed v6 or a copy of his home
system, look at /usr/dict/words. On the home system
that file is the wordlist from Webster's Collegiate
Dictionary, 7th edition, licensed for Bell Labs use
only. On distribution systems we substituted the wordlist
for "spell". The latter list contains many more proper
names, acronyms, etc than the dictionary did, in
particular names that appear in Unix documentation
such as Ritchie, Kernighan, and McIlroy. It also lacks
lots of trivially derivable words like "organizationally".
If you do have the Webster file rather than the spell
file, please don't propagate it.
