parse.y: fix here-doc identifier with newline
* parse.y (heredoc_identifier): quoted here-document identifier
must end within the same line.
the only corner case that here-document identifier can contain a
newline is that the closing qoute is placed at the beginning of
the next line, and has been warned since 2.4.
```ruby
<<"EOS
" # warning: here document identifier ends with a newline
EOS
```
