Log Message:
Update ruby-parser to 3.2.2.

=== 3.2.2 / 2013-07-11

* 5 bug fixes:

  * 1.9/2.0: fixed assocs in return args. (presidentbeef)
  * Fixed handling of parse error when class is nested in multiple defs. (whitequark)
  * Fixed lexing of %w[] w/ funny whitespace separators. (whitequark)
  * Fixed more call nodes that have trailing comma syntax. (presidentbeef)
  * Fixed more call_args slippage.

=== 3.2.1 / 2013-07-03

* 1 bug fix:

  * 1.9/2.0: Trailing assocs were being munged into arrays. (presidentbeef)

=== 3.2.0 / 2013-07-02

* 1 major enhancement:

  * Added (rough draft) 2.0 support. Still missing some small / rare things.

* 12 minor enhancements:

  * Added %i(symbol-names...) support. (%I too)
  * Added 140 more tests, jumping test count from 1376 to 2143. Yay for test reuse!
  * Added RubyLexer#brace_nest.
  * Added compare20 rake task to diff the grammar architecture against MRI.
  * Added lpar_beg and paren_nest to lexer to track state of parens in stabbies
  * Added shadow nodes for scoped block args.
  * Compound RubyParser now defaults to 2.0.
  * Fixed rake to < 10, because 10's file dependency handling is so very broken.
  * Made it possible to specify version in bin/ruby_parse_extract_error w/ -v \ 
18|19|20
  * Refactored to RubyParserStuff::ENCODING_ORDER to allow custom tweaking of \ 
encoding guessing. (samlown)
  * Switched `rake debug` to default to 2.0.
  * Translated some fixes across 1.8 and 1.9 from 2.0.

* 42 bug fixes:

  * 2.0: Fixed a number of block args scenarios w/ kwargs
  * 2.0: Fixed args_tail mismatching against lexer.
  * 2.0: Fixed assocs to return a hash node.
  * 2.0: Fixed f_block_kw production.
  * 2.0: Fixed f_block_kwarg production.
  * 2.0: Fixed handling of stabby proc args in parens.
  * 2.0: Fixed lexing of kwsplat nodes.
  * 2.0: Implemented kwsplat nodes.
  * Added tUBANG to lexer.
  * Apparently ruby doesn't warn for escaped octal that goes above 7. wtf.
  * Cleaned up a LOT of arg handling (block and defn, not calls) by using #args.
  * ESC_RE is set to unicode. This seems problematic. *shrug*
  * Either found a bug in MRI and/or fixed paren_nest count for []=? methods.
  * Extended IDENT_CHAR_RE on 1.9+ to top out at \u{10ffff}... because we NEED a \ 
million unicode chars.
  * Fixed % strings with interpolation.
  * Fixed BEGIN {} to return a sexp.
  * Fixed a[] += b. (stormbrew)
  * Fixed arg_blk_pass to allow for sub-args nodes.
  * Fixed assignable to allow for sexps to be passed to it.
  * Fixed assoc args in 1.9.
  * Fixed block_command and block_call (eg a.b c d) to #to_sym their args properly.
  * Fixed bug in compound RubyParser so it rescues RubyParser::SyntaxError.
  * Fixed env registration of cdecls.
  * Fixed lex value for { when expr_endfn.
  * Fixed lex_state for close paren/brace/bracket.
  * Fixed lex_state transition for 1.9 if we lexed a defn name. Only 1.8 is odd.
  * Fixed lexer problem with state mgmt of identifiers that also have registered \ 
var name.
  * Fixed lexing of "1 *\n" to have the correct lex_state.
  * Fixed lexing of heredocs vs chevron for some lex_states.
  * Fixed op_asgn nodes to #to_sym their args properly.
  * Fixed optional value block args.
  * Fixed parsing of __ENCODING__ on ruby 1.8 (vcall).
  * Fixed some oddity where 1.9 lexing was blowing up on "0o". Seems \ 
invalid now.
  * Fixed strings with escaped octals > 128. Also... wtf.
  * Fixed support for empty symbol (wtf?).
  * Lexer is now declared UTF-8 internally. Hopefully this will fix the encoding \ 
mess.
  * Made UTF_8 the default guess on encodings when it isn't explicit.
  * Parsing of __ENCODING__ on ruby 1.9+ (in ruby 1.9+) is now colon2 sexp. \ 
(whitequark)
  * Renamed RubyLexer#nest to string_nest
  * RubyLexer#unescape ignores bad octal/hex and returns unicode strings.
  * Switched a number of lexical constructs to use IDENT_CHAR_RE instead of \w. \ 
I wish there were something cleaner for regexps + unicode.
  * Switched ruby_parse_extract_error to use binread.
