  Log:
  SVN rev 210829 on 2010-08-03 22:17:29Z by jilles
  
  sh: Return 0 from eval if no command was given.
  
  This makes a difference if there is a command substitution.
  
  To make this work, evalstring() has been changed to set exitstatus to 0 if
  no command was executed (the string contained only whitespace).
  
  Example:
    eval $(false); echo $?
  should print 0.
