Bug #6211: Ripper lexes :on_rbrace when it should find :on_embexpr_end

=begin
  1.9.3-p125 :001 > require 'ripper'
   => true
  1.9.3-p125 :002 > Ripper.lex %Q{`\#{cmd}`}
   => [[[1, 0], :on_backtick, "`"], [[1, 1], :on_embexpr_beg, "\#{"], [[1, 3], :on_ident, "cmd"], [[1, 6], :on_rbrace, "}"], [[1, 7], :on_tstring_end, "`"]]

I'd expect (({[[1, 6], :on_rbrace, "}"]})) to be (({[[1, 6], :on_embexpr_end, "}"]})).

I also just noticed that there's similar behavior with backticks--the first gets parsed as such, but the last gets parsed as (({:on_tstring_end})).  This seems less obvious/important (?) compared to the embexpr stuff, as the type of embexpr tokens imply a beg & end; backticks don't imply beg & end, but, all the same, feel inconsistent.
