   Actually, this line is correct.  At least, for sh(1).
 
 ------------------------------------------------------------------------------
    Simple Commands
      If a simple command has been recognized, the shell performs the following
      actions:
 
      1.   Leading words of the form ``name=value'' are stripped off and
           assigned to the environment of the simple command.  Redirection
           operators and their arguments (as described below) are stripped off
           and saved for processing.
 -- (c) man 1 sh --------------------------------------------------------------
 
   An example:
 nx6125% /bin/sh
 $ echo $VAR
 
 $ VAR='tuesday' /bin/sh -c 'echo $VAR'
 tuesday
 $ echo $VAR
 
 $
