Subject: Mention the environment variables that affect the execution of uniq.
 Of particular interest is the fact that LC_COLLATE affects how uniq
 determines whether lines are equal. This was the subject of a fairly heated
 debate a year or so ago, and it turns out that the current behaviour is
 correct and that the standard contained an error.

Now that the standard has been corrected by Cor. 1-2002, refer to 1003.1-2001
instead of the 1992 edition in the Standards section.
