Removed duplicate assignment 
This `last_state` is set to `lex.state` just before the `switch`
statement, and `token_flush` nor `nextc` never change the state.

else if true

Do not dispatch a nil token in ripper 
As a comment token includes the newline, so delayed newline token
just follows it should not be dispatched.  [Bug #11485]

Fix memory leak 
* string.c (str_replace_shared_without_enc): free previous buffer
  before replaced.

* parse.y (gettable): make sure in advance that the `__FILE__`
  object shares a fstring, to get rid of replacement with the
  fstring later.
  TODO: this hack may be needed in other places.

f258137083 Fix grammar of macro name: ECCESSED -> ECCESSIVE

0872ea5330 node.h: Avoid a magic number to represent excessed comma 
`(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.

EOF by 2 ^D on a TTY 
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.
