Implement exec command

[shoyan]

Hello. checkstyle_filter-git is good product.

I found one bug that following.

⇒  vendor/bin/phpcs -n --report=checkstyle index.php | bundle exec checkstyle_filter-git diff origin/master
bundler: failed to load command: checkstyle_filter-git (/Users/shoyan/app/vendor/bundle/ruby/2.3.0/bin/checkstyle_filter-git)

A character encoding of index.php is EUC-JP.

I first had to customize the diff command. However, it did not work.
So I implemented exec command.

For example.

$  vendor/bin/phpcs -n --report=checkstyle index.php | bundle exec checkstyle_filter-git exec "git diff --no-color origin/master | iconv -f EUCJP -t UTF8"
<?xml version='1.0' encoding='UTF-8'?>
<checkstyle version='2.6.1'>
<file name='/Users/shoyan/app/index.php'>
 <error column='5' line='9' message='Expected 1 space after closing parenthesis; found 0' severity='error' source='Squiz.ControlStructures.ControlSignature.SpaceAfterCloseParenthesis'/>
</file>
</checkstyle>

Thank you for the quick response! Please refer to the following.

その他
ファイルのエンコードがEUC-JPのソースコードに適用したところエラーとなりました。
