`(ID)1` was assigned to NODE_ARGS#rest_arg for `{|x,| }`.
This change removes the magic number by introducing an explicit macro
variable for it: NODE_SPECIAL_EXCESSED_COMMA.
Terminate the input from a TTY by 2 ^D at the middle of line, like
as many programs, `cat`, `perl` and so on, do. By the first ^D,
the line will be sent without a newline, and then EOF will be send
by the next ^D.
* parse.y (here_document): broke the terminator condition down
into each piece, the positional condition, resetting the
dedented here-document indentation, and matching identifier.
suppress a false warning by icc.
Heredocs are parsed line-by-line, so we need to keep track of the
temporary encoding of the string. Previously, a heredoc would
only detect mixed encoding errors if they were on the same line,
this changes things so they will be caught on different lines.
Fixes [Bug #15839]
This allows cases such as:
```ruby
m ->(a = ->{@1}) {a}
m.call.call(1)
m2 ->(a: ->{@1}) {a}
m2.call.call(2)
```
Previously, this would cause a syntax error.
[Bug#15789]
Because `proc{|| @1}` is a syntax error, the following should
also be syntax errors:
```ruby
proc { |
| @1}
```
```ruby
proc { |; a| @1 }
```
This fixes both cases.
[Bug #15825]
* 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
```
* parse.y (internal_id): number the ID serial for internal use by
counting down from the neary maximum value, not to accidentally
match permanent IDs.
[Bug #15768]
* parse.y (parser_append_options): explicitly pass $; when auto
splitting, to suppress the warning for non-nil $;.

replaced accidentally. it is not the argument name.

* parse.y: show compile error and the error line separately,
instead of building the error message by snprintf then yyerror.
