  SVN rev 200943 on 2009-12-24 15:14:22Z by jilles
  
  sh: Remove setting variables from dotcmd/exportcmd.
  
  It is already done by evalcommand(), unless special-ness has been removed,
  in which case variable assignments should not persist. (These are currently
  always special builtins, but this will change later: command builtin,
  command substitution.)
  
  This also fixes a memory leak when calling . with variable assignments.
  
  Example:
    valgrind --leak-check=full sh -c 'x=1 . /dev/null; x=2'
