  SVN rev 210488 on 2010-07-25 22:25:52Z by jilles
  
  sh: Fix crash due to uninitialized here-document.
  
  If an ; or & token was followed by an EOF token, pending here-documents were
  left uninitialized. Execution would crash, either in the main shell process
  for literal here-documents or in a child process for expanded
  here-documents. In the latter case the problem is hard to detect apart from
  the core dumps and log messages.
  
  Side effect: slightly different retries on inputs where EOF is not
  persistent.
  
  Note that tools/regression/bin/sh/parser/heredoc6.0 still causes a similar
  crash in a child process. The text passed to eval is malformed and should be
  rejected.
