Two advantages:
- higher relevance of the extremely common word "heredocs" which may
help people find this page when searching for "ruby heredocs"
- the anchor link becomes `#label-Here+Documents+-28heredocs-29`, which is
ugly due to the parentheses but includes the word "heredocs" in the URL to
this section
If anyone knows a way to prevent RDoc from turning invalid characters into
ugly and meaningless ASCII codes, I'm listening. I don't want to break existing
anchor links but RDoc should really ignore these characters or turn them into
dashes.

* parse.y (heredoc_identifier): CR in here-document identifier
might or might not result in a syntax error, by the EOL code.
make a syntax error regardless of the EOL code.
* 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
```
Backslash goes first in escape sequences, so it must be
"any other character following a backslash is interpreted as ...",
while the doc says "...followed by...".
