  SVN rev 214304 on 2010-10-24 22:03:21Z by jilles
  
  sh: Do not allow overriding a special builtin with a function.
  This is a syntax error.
  
  POSIX does not say explicitly whether defining a function with the same name
  as a special builtin is allowed, but it does say that it is impossible to
  call such a function.
  
  A special builtin can still be overridden with an alias.
  
  This commit is part of a set of changes that will ensure that when
  something looks like a special builtin to the parser, it is one. (Not the
  other way around, as it remains possible to call a special builtin named
  by a variable or other substitution.)
  
  Exp-run done by:        pav (with some other sh(1) changes)
