Log:
  MFC	r238377:
  
  Merge libedit adjustment from NetBSD.
  
  On recent versions of NetBSD's libedit, el_gets
  now sets el_len to -1 on error so we can
  distinguish between a NULL string and an error.
  
  This fixes sh from exiting with newer versions
  of libedit now allowing EINTR to return.
