a short trip in the wayback machine

While following up a comment from Tom on my blog, I discovered that some 
9 1/2 years ago in a patch bearing the comment:
   Fixed psql double quoting of SQL ids   Fixed libpq printing functions     

the documentation of psql's --no-readline option was removed 
(psql-ref.sgml v 1.23). I think this was a mistake and it should be 
restored :-) I'm quite never sure how far back to take pure docs 
patches, though. Should I just fix HEAD, or HEAD plus 8.4, or all the 
way back to 7.4?

cheers
