Warnings in parser.rb

[cschneid]

I'm getting several warnings when I run my app that loads pry-inline.

I'm on Ruby 2.2.5

/Users/cschneid/.rvm/gems/ruby-2.2.5/gems/pry-inline-1.0.2/lib/pry-inline/parser.rb:33: warning: method redefined; discarding old on_parse_error
/Users/cschneid/.rvm/gems/ruby-2.2.5/gems/pry-inline-1.0.2/lib/pry-inline/parser.rb:14: warning: previous definition of on_parse_error was here

>> require 'ripper'
=> true
>> Ripper::Version
=> "0.1.0"

It looks like Ripper::PARSER_EVENTS contains a :parse_error token, which creates the on_parse_error function. But then towards the bottom of the file, there's an explicit on_parse_error definition that triggers this warning.

The fix is pretty simple (next if event == :parse_error in the first loop).
