  sh: Allow terminating a heredoc with a terminator at EOF without a newline.
  
  This is sometimes used with eval or old-style command substitution, and most
  shells other than ash derivatives allow it.
  
  It can also be used with scripts that violate POSIX's requirement on the
  application that they end in a newline (scripts must be text files except
  that line length is unlimited).
  
  Example:
  v=`cat <<EOF
  foo
  EOF`
  echo $v
  
  This commit does not add support for the similar construct with new-style
  command substitution, like
  v=$(cat <<EOF
  foo
  EOF)
  This continues to require a newline after the terminator.
