sh(1) man page bug(s?)

["Karl O. Pinc" <kop@meme.com>]

      A pipeline may be prefixed by
      the `!' reversed word which causes the exit status of the 
pipeline to be
      logically complemented: if the original status was 0 the 
complemented
      status will be 1; if the original status was not 0, the 
complemented sta-
      tus will be 0.

I believe this should be:
      the `!' reserved word
(isn't it a token?)

Meanwhile the next paragraph says there's a `|&' token, but
I've searched the whole document for | and & and can't
find any explanation of what this token does.  Am I missing
something?
