optparse: Suppress warnings

2018-05-06T09:53:33+00:00

Ruby warns "instance variable `@version` not initialized" for optparse when it receives `--version` option.

`test.rb`

```ruby
require 'optparse'
Version = '1'
OptionParser.new.parse(ARGV)
```

```
$ ruby -w test.rb --version
/home/pocke/.rbenv/versions/2.5.1/lib/ruby/2.5.0/optparse.rb:1168: warning: instance variable @version not initialized
/home/pocke/.rbenv/versions/2.5.1/lib/ruby/2.5.0/optparse.rb:1175: warning: instance variable @release not initialized
test 1
```

This change will suppress the warnings.

[Fix GH-1871]

Fix DecimalInteger converting to octal bug

2017-07-06T11:49:03+00:00

Previously if the input started with a '0' then it will be converted
as octal even though it has been specified as a decimal. This commit
forces the number to be interpreted as a decimal.
