  SVN rev 223163 on 2011-06-16 21:50:28Z by jilles
  
  sh: Reduce unnecessary forks with eval.
  
  The eval special builtin now runs the code with EV_EXIT if it was run
  with EV_EXIT itself.
  
  In particular, this eliminates one fork when a command substitution contains
  an eval command that ends with an external program or a subshell.
  
  This is similar to what r220978 did for functions.
